I made a fire Alarm circuit using BC547 Transistor , Circuit Diagramm at the end of the Video
#firealarmcircuit #firedetector
Components:
1x BC547 Transistor
1x LED
1x breadboard
1x Infrared LED
1x 9v Battery
1x 220 Ohm resistor
1x Buzzer
2x Jumper wires
Working principle :
The Infrared LED which is connected to the Base of the BC547 detects the infrared radiation from the fire, which gives a positive pulse to the Base of Transistor and the transistor turns on
Current can now flow from Collector to Emitter which makes the buzzer and the LED also turn on
Hence, at the end the fire will be detected
