Circuit and Working: This fire extinguishing robot is a prototype (Fig. 1) of the actual one. Sensors used here are simple infrared (IR) photodiodes that detect IR rays coming out of the fire. The ...

This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

Installation Instructions: Wiring: Follow the circuit diagram above to correctly connect the components. Upload the Code: Open the Arduino IDE, copy and paste the code above into the editor, and ...

Fire Detection – Sensors (temperature, smoke, and flame) continuously monitor the surroundings. Fire Confirmation – The system checks multiple sensor readings to reduce false alarms. Alert & ...

At the heart of this overhead detector (fire alarm) circuit is a precision integrated temperature sensor type LM35 (IC1), which provides an accurately linear and directly proportional output in mV, ...
