The document describes an NDIR gas sensing circuit designed by Rishav Pandey at CSIR-CEERI under the guidance of Dr. Ravindra Kumar Jha. The circuit uses components like an IR light source, optical filters, thermopile and thermistor IR detectors, op amps, a low noise amplifier, analog microcontroller, and voltage regulator. The PCB is designed to interface with an Arduino board. It uses AD8629 op amps to amplify sensor signals and an ADuCM360 microcontroller to control the lamp voltage and read the ADC outputs to analyze gas concentrations.

Navigation system for blind using GPS & GSMPrateek Anand
Currently, blind people use a traditional cane as a tool for directing them when they move from one place to another. Although, the traditional cane is the most widespread means that is used today by the visually impaired people, it could not help them to detect dangers from all levels of obstacles. In this context, we propose a new intelligent system for guiding individuals who are blind or partially sighted. The system is used to enable blind people to move with the same ease and confidence as a sighted people. The system is linked with a GSM-GPS module to pin-point the location of the blind person and to establish a two way communication path in a wireless fashion. Moreover, it provides the direction information as well as information to avoid obstacles based on ultrasonic sensors. A beeper, an accelerometer sensor and vibrator are also added to the system. The whole system is designed to be small, light and is used in conjunction with the white cane. The results have shown that the blinds that used this system could move independently and safely.

a mosquito repellent circuit to generate a frequency range between 20-38 kHz. As this particular frequency is known as ultra sound it distracts the female mosquitoes .To make this circuit we are using here IC-555 timer, variable resistor, capacitor and to generate this ultrasound frequency we are using piezzo buzzer.
This is all about the whole system which is capable the count the entry of threats to a particular secured area.
The final product will be the model of "laser security alarm". The project model consists of mainly two parts-
1. laser security alarm
2. person counter
Laser security alarm will notify that someone has trespassed secured area and analog counter will give the count that how many persons have trespassed that particular area.
This project will give us effective protected area to us. Once this protected area will be breached, the alarm will sound.
We made the laser security in low budget. It had been protect in full security. Laser security systems are a high tech technology that used to be a part of home security only available to the wealthy. It is manually switch dependent sensors and a basic alarm unit.
Laser has several advantages as compared to other light sources like cheap, less manpower; efficient, easily available, design is quite easy.
The liquefied Petroleum Gas (LPG) sensor is suitable for sensing LPG (composed of mostly
propane and butane) concentration in the air. This can be used in Gas Leakage Detection
equipment for detecting the ISO-butane, Propane, LNG combustible Gases. If output goes above
the preset range, indication will be shown as high otherwise it will remain in idle condition.
Here you will find details about how you can make a fire detection system by using arduino and flame sensor. We have also added the budget you need to make this project.
A Measurements Project on Light Detection sensorsvrohith 9
The main aim of this project is to saving system with LDR this is to save the power. We want to save power automatically instead of doing manual. So it’s easy to cost effectiveness. This saved power can be used in some other cases. So in villages, towns etc. we can design intelligent systems for the usage of light or we can also use this to reduce the electricity bill of our home. This project can also be used for security of the houses, banks, etc.
GPS & GSM based Voice Alert System for Blind Personijsrd.com
This paper presents a theoretical model and a system concept to provide a smart electronic aid for blind people. This system is intended to provide overall measures –object detection and real time assistance via Global Positioning System (GPS).The system consist of ultrasonic sensor, GPS Module, GSM Module and vibratory circuit (speakers or head phones). This project aims at the development of an Electronic Travelling Aid (ETA) kit to help the blind people to find obstacle free path. This ETA is fixed to the stick of the blind people. When the object is detected near to the blinds stick it alerts them with the help of vibratory circuit (speakers or head phones). The location of the blind is found using Global System for Mobile communications (GSM) and Global Position System (GPS).
Gas and smoke use every day of our life. A big number of accident happen today everyday life from the gas. A huge number of loss occur from gas and smoke in our everyday life. Gas speared so quickly that an accident happen so quickly.
So basically we try to modify our project to make a gas or smoke detector that will response with the present of smoke and send warning sms.

An encoder in digital electronics is a one-hot to binary converter. That is if there are 2ⁿ input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the n-bit output lines. A binary encoder is the dual of a binary decoder.

Patient Health Monitoring System Using Arduino & ESP8266Rishav Pandey
Sometimes it happens when patients struggles to find hospital beds but due to high number of covid patients they are forced to stay at home and aren't monitored by any doctor. This Health Monitoring System designed with the help of Arduino UNO board and ESP8266 wifi microchip helps the doctor to monitor the patient remotely (connected via an IoT based platform ThingSpeak). ESP8266 wi-fi microchip is used to provide internet connectivity to our project (or we can connect our project to any wifi using same). The system consists of a pulse sensor and and an LM35 temperature sensor which measures the patient's heart beats per minute and body temperature respectively. The Arduino reads the sensor data, converts them into string, passes them to the IoT platform (ThingSpeak) and also displays the BPM and body temperature on LCD display.
In this way a doctor can remotely monitor the patients and take appropriate actions when required.

3. CIRCUIT COMPONENTS….
The following components are used to design a
circuit diagram of basic NDIR system:
1. Lamp (An IR light source).
2. Active and Reference optical filters.
3. IR Detectors (consisting of Thermopiles and
Thermistor)
4. Two AD8629 Operational Amplifiers.
5. One ADA4528-1 low noise amplifier.
6. One ADuCM360 analog microcontroller (consisting
of ADCs, Muxes, etc)
7. One ADP7105 low drop regulator.
4. CIRCUIT EXPLANATION….
• The printed circuit board (PCB) is designed in an
Arduino shield form factor and interfaces to the EVAL-
ADICUP360 Arduino-compatible platform board. The
signal conditioning is implemented with the AD8629 and
the ADA4528-1 low noise amplifiers and
the ADuCM360 precision analog microcontroller, which
contains programmable gain amplifiers, dual 24-bit Σ-Δ
analog-to digital converters (ADCs).
• The thermopile sensor is composed of a large number of
thermocouples connected usually in series or, less
commonly, in parallel. The output voltage of the series
connected thermocouples depends on the temperature
difference between the thermocouple junctions and the
reference junctions.
5. CONTINUED….
• The circuit uses the AD8629 op amp to amplify the
thermopile sensor output signals.
• The ADP7105 low dropout regulator generates a stable
5 V output voltage to drive the lamp, and is turned on
and off by the ADuCM360.
• In the NDIR application, pulsed and filtered IR light is
applied to the series connected active junctions; the
junctions are therefore heated, which in turn generates a
small thermoelectric voltage. The temperature of the
reference junction is measured with a thermistor.
