The document describes an intelligent street lighting system using GSM technology. It consists of microcontroller-based nodes installed on each street light that monitor light levels, pollution, noise and weather conditions. The nodes send this sensor data wirelessly to a central control system using GSM. The control system can then automatically or manually adjust street light brightness and schedule based on the sensor readings to improve efficiency. This helps reduce energy consumption from street lights by 40% while also lowering maintenance costs and extending bulb lifetimes.

Every evening, an intelligent street lighting control system has to light up at the right time and function seamlessly. A city’s street lights provide safer traffic conditions, safer pedestrian environment and can represent a great improvement to the city’s architectural, touristic and commercial output. These benefits are not exactly cheap though, with an average of 40% of the public budgets’ energy bill being spent for street lighting alone. The increasing energy price, plus the significant maintenance costs and always increasing expectations manifested by the public put a continuous pressure on the lighting budgets.
inteliLIGHT® is a remote street lighting control solution that offers you detailed, lamp-level management capabilities of every street light in your city and ensures that the right amount of light is provided where and when needed. Equally important, in-depth grid management gives an accurate real-time feedback of any change occurring along the grid, reduces both energy loss and energy surges and offers advanced maintenance optimization tools. Using the existing infrastructure, you can have live detailed information over the grid and transform the existing distribution level network into an intelligent infrastructure of the future
In this project, the data can be transmitted to and received from remote Zigbee communication device. Data Security is primary concern for every communication system.

Energy efficient smart street light for smart city using sensors and controllerjournalBEEI
Smart street light is an intelligent control of street lights to optimize the problem of power consumption of the street, late in night. Conventional street lights are being replaced by Light Emitting Diode (LED) street lighting system, which reduces the power consumption. The focus of this project is to design a system of street lights controller to provide a reduction in power consumption. The prototype was designed by using Light Dependent Resistor (LDR), Infrared sensor (IR), battery and LED. The brightness of the lamps is being controlled in this project to reduce the power consumption. The dimming of the lamps depends on the speed of object motion detected such as pedestrians, cyclists and cars. The higher speed of moving object, the greater the level of intensity. For this idea, the innovation of street lights is not quite the same as conventional street lights that are controlled by timer switch or light sensor which automatically turns light on during sunset and off during sunrise. According to the study, motion detection devices may help to save up to 40% of energy per month.
Many of the people have a phobia of darkness, so to assist them in such situation, we have explained a simple circuit. It will automatically turn on street light in the way of LEDs or bulb coupled with relay. Working this circuit is very much easy and also the power consumed by the circuit is very low because of the very few components used in the circuit.

The project "STREET LIGHT MONITORING AND CONTROL SYSTEM" is developed for automatic
street lights maintenance and to reduce power consumption. The application is designed in such a way that we
place light sensors in all street light circuits, which is responsible to switch on and off automatically. once the
lights are switched on current sensors placed at every street light circuits are responsible to report problem status
to the centralized system with help of GSM module attached with the circuit. The status is available in the
centralized system, the work man now can easily locate the particular light to take care which minimizes the time
to search it and repair. The system also maintains database to store useful information from each street light like
power consumption, total number of burning hours, total number of interruptions, tally the actual power
consumption with the power supplied and details of fault detection. Hence maintaining the system with optimal
power consumption giving commercial benefits to business and the prosperity of the city as a whole.

The paper introduces a system by which we are capable of controlling the usage of electricity to a greater extent. In this system the customer is able to know about the per day consumption of electricity. It also informs the user if any intruder breaks in or about gas leakage while the user is away from the household. In this, we use PIC 16F877A microcontroller, in order to calculate the per day consumption, also a relay network is used to control the appliances/devices connected to it. The presence of intruder and gas leakage is noted with the help of sensors attached with the module. The module as a whole performs automation of home.
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

INTRODUCTION
GSM based street light monitoring & control system is an automated system
designed to increase the efficiency and accuracy of an industry by automatically timed
controlled switching of street lights. GSM based street light monitoring & control system
consists of an 89C51 microcontroller which on setting of time delays switches ON/OFF the
street lights and sends the update through a phone to the specified phone number. This is
smart way of managing street lighting systems. There are basically two modules which
include the client side and the server side. The client side consists of the GSM modem
which is further connected to the microcontroller. The server side consists of the JAVA
based web server it has a core engine which interacts with the user, database and the GSM
communication manager.
1.1 Overview
Due to the increase of environmental concerns, lighting control systems will play an
important role in the reduction of energy consumption of the lighting without impeding
comfort goals. As mentioned the energy is the single most important parameter to consider
when assessing the impacts of technical systems on the environment. Energy related
emissions are responsible for approximately 80% of air emissions and central to the most
serious global environmental impacts and hazards, including climate change, acid
deposition, smog and particulates. Lighting is often the largest electrical load in offices, but
the cost of lighting energy consumption is low when compared to the personnel costs. Thus
its energy saving potential is often neglected.
According to study global grid based electricity consumption for lighting was about
2650 TW in 2005, which was an equivalent of 19% of total global electricity consumption.
European office buildings dedicate about 50% of their electricity for lighting, whereas the
share of electricity for lighting is around 20-30% in hospitals, 15% in factories, 10-15% in
schools and 10% in residential buildings..Intelligent lighting control and energy
2. Intelligent Street Lighting System Using GSM 2014-15

management system is a perfect solution for energy saving, especially in public lighting
management. It realizes remote on/off and dimming of lights, which can save energy by
40%, save lights maintenance costs by 50%, and prolong lamp life by 25%. The system
application in streetlight control for each lamp will reduce in streetlight electricity and
maintenance cost, and increase availability of street light.
1.2 Unique Characteristic
Detecting failures of any node.
Tolerance to communication network.
Dynamic network topology.
Each node in the network is linked to the main server via a protocol. The analog data
sensed by the sensor is converted in digital form, processed by microcontroller and then sent
to the server. The master controls all the slaves .The other nodes sends the data to master
and the master collects the data and further sends to concentrator and server where the data
is monitored and on necessary alterations process it to switch On/Off the nodes devices.
This scenario increases life of streetlights, reduces power consumption, ease of monitoring
and controlling and less installation cost are the various advantages achieved.
1.3 Methodology
Firstly, Chips would be made to be installed on the lights. These chips will consist of
a micro-controller along with various sensors like CO2 sensor, fog sensor, light intensity
sensor, noise sensor and GSM modules for wireless data transmission and reception
between concentrator and PC. The data from the chips would be received on a remote
concentrator (PC) and the PC would also transmit the controlling action to the chip.
According to the survey of variation in the intensity of light in the field area, efficient
programming would be done to ensure minimum consumption of energy. The emissions in
the atmospheres would be detected along with the consumption of energy and any theft of
electricity.

LITERATURE SURVEY
2.1 Survey Papers
A Street light, lamppost, street lamp, light standard, or lamp standard is a raised
source of light on the edge of a road or walkway, which is turned on or lit at a certain time
every night. Major advantages of street lighting includes: prevention of accidents and
increase in safety. Studies have shown that darkness results in a large number of crashes and
fatalities, especially those involving pedestrians; pedestrian fatalities are 3 to 6.75 times
more likely in the dark than in daylight. Street lighting has been found to reduce pedestrian
crashes by approximately 50%.A number of street light control systems have been
developed to control and reduce energy consumption of a town's public lighting system.
These range from controlling a circuit of street lights and/or individual lights with specific
ballasts and network operating protocols.These may include sending and receiving
instructions via separate data networks, at high frequency over the top of the low voltage
supply or wireless.
Various protocols have been developed as well as compatible hardware for most
types of lighting. The control center will deal with the data so that it can know the situation
of each streetlight. GSM based street light monitoring & control system is an automated
system designed to increase the efficiency and accuracy of an industry by automatically
timed controlled switching of street lights. GSM based street light monitoring & control
system consists of an 89C51 microcontroller which on setting of time delays switches
ON/OFF the street lights and sends the update through a phone to the specified phone
number.There are basically two modules which include the client side and the server side.
The client side consists of the GSM modem which is further connected to the
microcontroller. The server side consists of the JAVA based web server; it has a core engine
which interacts with the user, database and the GSM communication manager[1].
Street light, a raised source of light that is commonly used along walkways and
streets when the surrounding turns dark. Currently, various street lighting control systems
technology have been developed to control and maintain these systems more economically.
4. Intelligent Street Lighting System Using GSM 2014-15
Dept. of CSE, MIT Mysore 4
However, most of these systems developed have contributed some drawbacks. They have
been considered to be outdated due to lack of communication capabilities, not allowing a
system feedback. Hence, Zigbee communication technology is deployed so as to ensure a
higher efficiency and overcome current drawbacks. The system will be able to detect fault
and apprise the control room about it. Zigbee -enabled street light is based on the wireless
sensor network application that utilizes Zigbee communication protocol to enhance the
technology of street lighting system by providing communication capabilities. Zigbee –
enabled street light are mostly battery powered, hence there is no need of laying
underground cable connection.
As the surrounding gets darker, the resistance of the LDR (Light Dependent
Resistor) increases, the voltage yielded will be high and a large ADC (Analog to Digital
Converter) value will be obtained. The ADC value can be as low as 0 for very bright
environment and as far as 1023 for a dark environment. The ADC value obtained is directly
proportional to the voltage divider value of both the LDR and the potentiometer in series
with each other. A slightest change in the resistance of the LDR can give a difference to the
ADC value. The microcontroller used in the system is of 10-bit, hence produces as much as
210 = 1023 values[2].
Street Light Control System which operates automatically is not only easiest but also
the intelligent system. This system can be set to operate in automatic mode, which regulates
the streetlight according to brightness and dimness Algorithm and light intensity.

street light system also includes a time cut-out function, and an automatic control
pattern for even more electricity conserving, when vehicles pass by, the light will turn on
automatically, later turn off. Furthermore, this system has auto-alarm function which will set
off if any light is damaged and will show the serial number of the damaged light, thus it is
easy to be found and repair the damaged light. In addition, the system integrates a digital
temperature and humidity sensor, not only monitoring the streetlight but also temperature
and humidity The core of the system is constructed based on the Microchip’s PIC18F
microcontroller [3].
It aims at designing and executing the advanced development in embedded systems
for energy saving of street lights. Nowadays, human has become too busy, and is unable to

find time even to switch the lights wherever not necessary.The present system is like, the
street lights will be switched on in the evening before the sun sets and they are switched off
the next day morning after there is sufficient light on the roads. this paper gives the best
solution for electrical power wastage. Also the manual operation of the lighting system is
completely eliminated.In this paper the two sensors are used which are Light Dependent
Resistor LDR sensor to indicate a day/night time and the photoelectric sensors to detect the
movement on the street. The microcontroller PIC16F877A is used as brain to control the
street light system, where the programming language used for developing the software to the
microcontroller is C-language. Finally, the system has been successfully designed and
implemented as prototype system.
It elaborates the design and construction of automatic street control system circuit.
Circuit works properly to turn street lamp ON/OFF .After designing the circuit which
controls the light of the street as illustrated in the previous sections. LDR sensor and the
photoelectric sensors are the two main conditions in working the circuit. If the two
conditions have been satisfied the circuit will do the desired work according to specific
program. Each sensor controls the turning ON or OFF the lighting column.The street lights
have been successfully controlled by microcontroller with commands from the controller the
lights will be ON in the places of the movement when it's dark. Furthermore the drawback
of the street light system using timer controller has been overcome, where the system
depends on photoelectric sensor. Finally this control circuit can be used in long roadways
between the cities [4].

3.1 WSN For Intelligent Street Lighting System
Wireless Sensor Network (WSN) is a wireless network consisting of spatially
distributed autonomous devices using sensors to cooperatively monitor physical or
environmental conditions, such as temperature, sound, vibration, pressure, motion or
pollutants, at different locations In addition to one or more sensors, each node in a sensor
network which typically equipped with a radio transceiver or other wireless communications
device, a small microcontroller, and an energy source, usually a battery.
A sensor network normally constitutes a wireless ad-hoc network, meaning that
each sensor supports a multi-hop routing algorithm (several nodes may forward data packets
to the base station).
Types of Sensor Nodes
1. LDR [Light Dependent Resistors] sensor
2. CO2 gas sensor
3. Sound sensor
1. LDR [Light Dependent Resistors] sensor:
LDRs or Light Dependent Resistors are very useful especially in light/dark sensor
circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000
000 ohms, but when they are illuminated with light resistance drops dramatically.
When the light level is low the resistance of the LDR is high.

2. CO2 gas sensor:
The CO2 Gas Sensor Module is designed to allow a microcontroller to determine
when a preset Carbon Dioxide gas level has been reached or exceeded. Interfacing
with this sensor is done through a 4-pin SIP header and requires two I/O pins from
the host microcontroller. The sensor module is intended to provide a means of
comparing gas sources and being able to set an alarm limit when the source becomes
excessive.

3. Sound sensor:
The Sound sensor module is a simple microphone. Based on the power amplifier
LM386 and the electronic microphone, it can be used to detect the sound strength of
the environment. The value of output can be adjusted by the potentiometer.

successful establishment of connection it gives timing details and address of device.
4.4.2 Receiving node list from the network
After providing the Network parameters to the System the system sets up the
Network. If new nodes are added to the network then, the system takes a small period of
time to detect new nodes and add them to the network. The nodes broadcast its “HELLO”
16. Intelligent Street Lighting System Using GSM 2014-15
Dept. of CSE, MIT Mysore 16
message which is subsequently received by the Master Node. The node detection is verified
by the “List Receive Message”.
4.4.3 Viewing the Node List of the nodes present in the Network
After the complete setup of the network the Nodes present in the network are
presented to the administrator. The Nodes are represented by their node number, their
current status and also the number of nodes present in the Network.
4.4.4 Set status of a particular node
Administrator can Select a particular node and update its status i.e. ON/OFF. The
administrator provides the necessary command to set the Node ON and OFF. A value 1 is
entered as a command by the Administrator to turn the Street node ON and value 0 is
entered as a command to turn the Street node OFF.
