How to make fire detector using BC547 projects
Today I am going to make a circuit of Simple rain alarm circuit using BC547 Transistor. This circuit is very easy to make.
Connect all components according to the circuit diagram.
Make PCB like this as schematic is in circuit diagram.
Solder +ve pin of buzzer to emmiter pin of the transistor as solder in the picture.
Next we have to connect the LED to the circuit.
Solder +ve leg of LED to -ve pin of the Buzzer as shown
Next solder Battery clipper wire to the circuit.
Solder +ve wire of battery clipper to collector pin of transistor and
-ve wire of battery clipper to -ve leg of LED as you can see
Solder wires in collector and base pin of the transistor.
Now solder wires of base and collector of transistor to the PCB Board according to the circuit diagram.
Now our circuit is ready.
Drop some drop of water/when water will fall down on the PCB Board then we will observe that LED is glowing and Buzzer will give sound.
This type we can make rain alarm circuit using NPN transistor BC547.
