Is there any person who comes to ON/OFF these lights? The above circuit performs that operation. Get complete details about this circuit in the link mention in the beginning of this description.

Light Activated Switch Circuit Working with Applications

In case of the street lights erected on highways it is not an easy task to manually control them, but, if uncontrolled, the chances of power wastage would increase. To get rid of this situation, the implementation of automatic light switch by using a light sensor that switches lights automatically on and off is the best option. Light Sensor

Automatic Night Lamp using LDR - electroSome

Automatic night lamp as the name suggests is for turning ON and OFF the lamp automatically without the need of human interventions. It senses the light intensity from surroundings and find whether its day or night.

Automatic Led Street Light Using Electronic Ldr Sensor Lights Switch - Image Results

Automatic led night light switch |

In case of this automatic LED night light switch, we should save energy so I design this with main parts below: 1. LDR or photoresistor is used for sensor light-activated. It is cheap and easy to use. 2. A CMOS Digital-IC No.CD4069 is a inverter gate every useful and cheap.

Dark/Light sensor using transistor | BuildCircuit - Electronics

As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1. Dark sensor with variable resistor: A dark detector can be made using a variable resistor. The sensitivity of the circuit can be adjusted with a variable resistor. High resistance-> more darkness to switch on the LED.
