Introduction: Touch Sensitive Switch
About: Hai my name is darsika and electronics circuit's making is my passion and i love this very much...
This is a very simple circuit
And
It's also called as Rain sensor
And
It's also called as Rain sensor
Supplies
All are available in local markets.or online .
Step 1: How to Connect
Dear all
This circuit called as Darlington paired amplifier as per the connection u connect all the component
U just made a touch sensitive switch
U can use single transistor circuit also...
Bc547 is a npn transistor
T1 Emitter connection goes to T2 base and T1 colector goes to T2 colector
T1 base is the input of the circuit
T1 base connection goes to connect with 1k and 100k
1k resistance next end is the input of the circuit...
100k another pin goes to ground
T2 Emitter goes to gnd
12 v possitive of the circuit and 1k resistance end is the inputs of circuit
You just touch the wire ... Led will glow u can connect buzzers also...instead of LED
