This circuit triggers the buzzer whenever it detects smoke or fire near by it.

Simple circuit diagram of fire alarm. 5v power supply. This means that a small change in temperature will cause a large change in its internal. In this article we will study the method to built a simple fire alarm by using a 555 timer ic. Circuit diagram components required timer ic 555 thermistor 103 ntc buzzer 5v transistor bc547 variable resistor 100kw resistor 100kw 2 resistor 1kw 4.

Circuit is a simple circuit that activates the circuit and sounds the buzzer after the temperature of the surrounding has increased to a certain level. The circuit diagram of this simple fire alarm project is shown in the following image. Simple fire alarm circuit using thermistor and op amp circuit diagram components required project construction output and working of the project. This sensor will be used to detect the fire.

This simple fire alarm circuit can be used as a indicator or warning circuit for excessive fire and temperature you can connect relay at the output to connect or disconnect target device. Mq6 gas sensor is also sensible to lpg alcohol and methane etc. These are very important devices to detect fire in the right time in todays world and prevent any kind of destruction to life or property. Nowadays almost all the important industrial and commercial buildings have been installed.

For more information on this simple fire. 1 x lm358 operational amplifier op amp 1 x 47 kw resistor 14 watt 1 x 10 kw potentiometer. 1 x 10 k thermistor. It is a resistor that is very sensitive to temperature.

1 x small buzzer 5v buzzer connecting wires. This circuit mainly uses mq6 smokegas sensor to detect the level of smoke. It will detect the fire and sound a buzzer. There are several useful applications and projects starts with the basics of electronicsthe basic electronics projects that are easy to make and have so many effective applicationshere is the project about fire detection alarm system basic circuit.

A thermistor is the heart of this circuit. Simple fire alarm circuit fire detector system basic electronics project. Simple fire alarm circuit designed by using 10k ntc negative temperature coefficient thermistor and timer ic 555 this circuit will produce buzzer sound when the temperature near thermistor raises beyond threshold and this threshold limit can be varied by using variable resistor.
