Fire and smoke detector system Project with Circuit Diagram

fire and smoke detector system

There are several useful applications and projects for engineering. The fire and smoke detector system project is easy to make and have so many effective applications. Here is the project about fire detection alarm system basic circuit. This is the bread board based temperature sensor using thermistor Project. A thermistor based project for fire detection.

This is the basic circuit project we will see how we can make sensor module based fire alarm circuit in the coming posts. A thermistor based fire detector system circuit is easy to make and cheapest in price. This project is also good for home based fire security and the similar fire detecting applications.

01. Fire and smoke detector System


To detect the fire and turning on the alarm. The output of the fire and smoke detector system is the buzzer when ever the thermistor detects heat and temperature of fire the buzzer will turn on.

03. Pinout Configurations


There is Transistor BC548 Connected with buzzer and Resistor. Transistor BC548 needs a pin-out configuration. A simplest and common transistor. The center leg of the transistor is the base and the last one is the emitter. The potentiometer has 3 legs the very first is the input voltage ,the center is the output an the last is the ground(GND).See the following fig. for pinout configurations.

05. Working of the Project



06. Results


The Buzzer will be turned on when ever a fire or heat in front of thermistor. To test the circuit of fire and smoke detector system light up a candle in front of thermistor and Adjust the POT Value to measure the output results.
