auto on off night lamp wiring diagram connection
Utsource is a professional electronic components supplier.
More than 800 original brands, More than 6 million original products
Required Components:
1.1 Pcs 0.22uF, 250V non polarized polyester capacitor
2.1 Pcs 560 Kilo Ohm, 1/4 Watt Resistor
3.1 Pcs 0.1uF, 100V Ceramic Capacitor
4.1 Pcs 2.2 Mega Ohm, 1/4 Watt Resistor
5.A 230V Light(CFL or any other lamp)
6.A 230V AC Power Source
7.1 Pcs BT136 TRIAC IC
8.1 Pcs DB3 DIAC
9.1 Pcs LDR
In our busy life, many of us forget to switch off the morning light. By using this simple circuit, the light will “automatically switch on” at night and “automatically switch off” in the morning.
Components Needed
1. Bread Board
2. LDR (Light Dependent Resistor)
3.Relay 6 volt DC (SPDT)
4. Diode 1N4001
5. Resistor 1K and 330R
6. Transistor BC547 (2)
7.Bulb
Connect one end of the LDR with Vcc and another end with one end of Resistor 330 ohms. Connect the other end of resistor with Ground.
Connect LDR with Base pin (i.e., 2nd pin) of Transistor BC547.
Connect 1K resistor with Vcc and another end with Collecter pin (i.e., 1st pin) of Transistor BC547.
Connect the Emitter pin (i.e., 3rd pin) of Transistor BC547 with Ground Voltage
Connect the Collector pin of Transistor BC547 with Base pin of another Transistor BC547
Connect the Emitter pin with Ground Voltage
Connect cathode side of Diode 1N4001 with Vcc.
Connect anode side of same Diode with Collecter pin of Transistor BC547.
Connect 'A' terminal of 6volt (SPDT) relay with Vcc and 'B' terminal with Diode's anode side.
Cut any one of the two terminals of the Bulb's wire in order to connect it with the relay.
Connect one wire with 'POLE' and another with 'NO' of the relay.
Connect the circuit with 6volt DC.
Don't switch on the circuit now.
(Now you are going to play with 230 Volt AC current, this is the risky step in this project, please do this with caution. Or otherwise please don't continue.)
Connect the Bulb with the 230v AC.
Now switch on the power supplies of the circuit, both 6v DC and 230v AC.
If your circuit is in dark, the Bulb lights automatically
If your circuit is in light, the Bulb automatically switches to off.
