Description
ABSTRACT
This work is on a PIN diode based fire sensor that activates an alarm when it detects fire. Thermistor based fire alarms have a drawback; the alarm turns on only if the fire heats the thermistor in close vicinity. In this circuit, a sensitive PIN diode is used as a fire sensor for longer-range fire detection.
PIN diode based fire sensor detects visible light and infrared (IR) in the range of 430nm – 1100nm. So visible light and IR from the fire can easily activate the sensor to trigger the alarm. It also detects sparks in the mains wiring and, if these persist, it gives a warning alarm.
