How to make 220v dark sensor circuit
In this project we learn How to make 220v dark sensor circuit easy at home. or How to make auto street light on off circuit on 220v easy at home.
|How to make 220v dark sensor circuit|
its very easy and simple project using few steps with circuit diagram. some time in evening when sun light dim then street light automatic on. because in street light they use LDR. For making this project we need some come components.
- BT136 TRIAC
- DB3 Diac (Trigger Diode)
- 100K 1Watt Resistor
- 100K Variable Resistor
- PCB Board
- Soldering iron
- Soldering wire
- Bulb Holder
- Bulb 220v
You can learn basic idea about electronic components simple clicking links.

BT136 TRIAC has three pin. 1st is terminal 1 2nd is terminal 2 and 3rd is gate. connect one side of DB3 with gate and 2nd side with middle pin of variable resistor. now connect LDR with T1 and 3rd pin of variable resistor. now connect 100k resistor with variable resistor. T2 and 2nd side of resistor use for output. T1 and 2nd side of 100k resistor use for input 220v power.
we learn it more better watching video.
