Make a Fire Alarm in your own hand.

By IKTech May 31, 2017

Fire Alarms Requirements – The fire is caused by massive damage. Many people fall away prematurely, many resources are destroyed. This fires are mostly due to our carelessness. Fire Alarms for this unnecessary fire that can be controlled quickly. A modern electronic technology to combat firefight challenges
Required components:

Capacitor 10uF – 1
Registry 1KΩ – 1
Variable Registry 10 KΩ – 1
Transistor (BC547 / BC548 / C828 / D400) – 1
Diode (1N4007 / 1N4148) – 1
Buzzer / LED – 1
Small light inside the thermostat or tube light starter – 1

Circuit diagram


Fig .: Fire Alarm Circuit

There is a transistor in the circuit. It’s basically working as a switching circuit.
Here we can use the small light inside the tube light starter instead of the thermoster.
That will work as our sensor.
Whenever the sensor takes fire or heat, the LED or the market in the circuit will signal.
Therefore, the thermoster / starter will be kept in a place where there is a possibility of fire. Such a warehouse, near the house electric key or main switch, in the kitchen.

Thermist means thermal registers. By knowing the name, it is understandable that its resistance is variable with the change in temperature.

Different types of thermostats

Different types of thermostats

There are 1 variable variation in the circuits, which can reduce the circuit’s sensitivity by doing less. This is to use the thermostat. There is no need for starter.
Some changes

You can use the market or relay instead of the LEDs.
You can use any standard diode in the circuit.
And beforehand, you can use small lights inside the station instead of the thermoster.

Diameter, you got your fire alarm project. Hope everyone can easily understand.

Why is it late? The project is ready today.
