Fire Security Alarm Circuit Without Transistor

Hii friend,

Today I am going to make a fire alarm circuit without using any transistor.

Let's get started,

Components required -

(1.) Battery - 9V x1

(2.) Battery clipper x1

(3.) Buzzer x1

(4.) IR Sensor x1

(5.) Match

Connect +ve wire of IR Sensor to the +ve of buzzer as shown in picture.

Now connect +ve wire of battery clipper to -ve of IR Sensor and

-ve wire of battery clipper to -ve of buzzer as shown in picture.

Now connect battery to the circuit and use it.

Burn fire across this circuit then buzzer will give beep sound.

Uses:- This circuit will help us to protect from fire.
