Our project “GSM based Garbage Disposal” is mainly intended to control the ON/OFF operations of the irrigation motor by using a mobile phone. The mobile phone present in the system uses auto answer function to lift the call. Each key in the mobile phone transmits two tones with different frequencies when pressed. These transmitted frequencies are decoded using DTMF decoder and the decoded value is fed as input to micro controller which in turn operates switches like Relay and Triac to which the irrigation motor is connected. The input value to the micro controller will be checked and respective operation of that key will be performed like switching ON/OFF the irrigation motor. The system also gives feed back through buzzer alarm system.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

3. Sensors
A sensor, is a device whose task is to detect events or changes in its immediate environment and convert these physical phenomena
(like temperature, light, air humidity, movement, presence of chemical substances and many others) into electrical impulses which
then can be meaningfully interpreted.
Sensor
‘Detector’
Physical
phenomena
Electrical
impulses
4. Actuators
An actuator, on the other hand, can be seen as a tool which functions inversely to the sensor. By interpreting the electrical impulses sent
from the control system and converting them into mechanical motion, it actually introduces changes to its physical surroundings by means of
a variety of simple actions, including but not limited to opening and closing valves, changing other devices’ position or angle, activating them
or emitting sounds or light. In simpler terms, the actuator is referred to as a ‘mover’.
Actuator
‘Mover’
5. •Thermistor: a type of resistor, whose resistance (resistance) depends significantly on the temperature.
Thermistors are widely used as sensors in electronics, e.g. as temperature sensors in electronic thermometers
or in systems preventing excessive current increase.
•Resistance temperature detectors: instruments for measuring temperature based on a change in
resistance that is associated with temperature changes.
•Thermocouples: elements of an electric circuit consisting of two different conductors. By using the fact
that the electromotive force that arises between the connectors of a thermocouple is proportional to the
temperature difference, thermocouples can be used as temperature sensors or sometimes even as a power
source with very low voltage and relatively high current.

7. Types of humidity sensors:
- Capacitive
A capacitive humidity sensor measures relative humidity by placing a thin strip of metal oxide
between two electrodes. The metal oxide’s electrical capacity changes with the atmosphere’s
relative humidity. Weather, commercial and industries are the major application areas.
- Resistive
Resistive humidity sensors utilize ions in salts to measure the electrical impedance of atoms. As
humidity changes, so do the resistance of the electrodes on either side of the salt medium.
- Homes. A humidity sensor is also found as part of home heating, ventilating and air
conditioning systems (HVAC systems).
These are also used in offices, cars, humidors, museums, industrial spaces and greenhouses and
are also used in meteorology stations to report and predict the weather.
Humidity sensors
8. •Photoresistor: it’s a photosensitive element, whose resistance changes through radiation. It can easily
be connected to for example Arduino as an analog light sensor. Thanks to this it is possible to build e.g.
lamps that turn on automatically after dark
•Photodiode: a diode which works based on photoelectric effect. When photons reach the junction of a
photodiode they are absorbed, which results in the electron being transferred to the conductivity band to
create an electron-hole pair. Photodiodes are widely used in industrial automation (signaling and control
systems), telecommunications (optocouplers, optoelectronic links) and many more industries.
•Depending on ambient light intensity, smart TVs, mobile phones or computer screens are able to adjust their
brightness thanks to light sensors, yet sensors for detecting ambient light are not only commonplace in
consumer electronics, but also smart city applications.
9.
10. •Active, ultrasonic motion sensor: sending and receiving ultrasonic passive waves
•Passive, infrared motion sensor: detecting changes in infrared radiation
•Active, radar sensor: emitting and receiving electromagnetic waves
A smart building system is probably the most banale IoT application for the motion sensor to imagine. While
this obviousness holds largely true, apart from helping to monitor private or public spaces from intrusion and
burglary, the use of motion sensors is extending to energy management solutions, smart cameras,
automated devices and many others.
13. •Linear actuators – these are used to enable motion of objects or elements in a straight line.
•Motors – they enable precise rotational movements of device components or whole objects.
•Relays – this category includes electromagnet-based actuators to operate power switches in lamps,
heaters or even smart vehicles.
•Solenoids – most widely used in home appliances as part of locking or triggering mechanisms, they also
act as controllers in IoT-based gas and water leak monitoring systems.

Voltages
Two 5V pins and two 3.3V pins are present on the board, as well as a number of ground pins (0V), which are unconfigurable. The
remaining pins are all general purpose 3.3V pins, meaning outputs are set to 3.3V and inputs are 3.3V-tolerant.
Outputs
A GPIO pin designated as an output pin can be set to high (3.3V) or low (0V).
Inputs
A GPIO pin designated as an input pin can be read as high (3.3V) or low (0V). This is made easier with the use of internal pull-up or pull-
