Diy fire alarm circuit
In this video i'm showing you, how to make fire detector alarm circuit at home, using Infrared Receiver.
Since the primary source of infrared radiation is heat or thermal radiation, any object which has a temperature radiates in the infrared.
Where IR Receiver detects the infrared radiation and due to change in conductivity of "IR Receiver" it passes some positive charge from cathode to anode that is connected to base of transistor that turns on negative charge from emitter to collector,
So, the buzzer starts giving beep sound.
Also LED Starts Glowing.
