Introduction to LDR Street light control

LDR sensor is used for detecting the presence of surrounding light so that during the day time when sun is bright, the street light is switched off automatically. During the night time when there is no light, the LDR sends signal to microcontroller to turn on the street light.

This project  done with pic Controller so we can adjust accuracy using POT  , Output relay is 230vac / 5 amps
