 Electricity sensor circuit using BC547 . transistor

 I have made a simple touch sensor circuit using the BC547 transistor on the breadboard. This touch sensor can be used as both touch sensitive light switch and door bell. I have also explained the working principle of the touch switch circuit.

I will request you to watch the complete tutorial video of the touch sensor project but you can also jump to any topic by click on the following Time Stamps: 

00:34   How to design a simple touch sensor circuit using transistors

03:31   How to make touch sensitive door bell

04:30   Working principle of the touch sensor switch

Components Required for the touch sensor:

1. BC547 transistor    2no

2. 10K ohm resistor    1no

3. 220-ohm resistor    1no

4. LED or DC buzzer

5. 9 volt Battery

6. Connecting wires

7. Breadboard

Here I have made a simple touch sensitive switch using BC547 NPN transistor and I have explained the working of the touch switch using the touch switch circuit diagram for better understanding that how the touch sensor works.
