Ldr is a photoresistor that is used for the detection of light.
Light sensor on off switch circuit.
A simple touch on and off switch circuit.
By using this light sensor circuit we can eliminate manual switching as the loads can be controlled automatically based on the daylight intensity.
Dark light activated circuit using ldr.
A few light sensor circuit based projects can be listed as a solar highway lighting system with auto turn off in daytime security alarm system by photo electric sensor sunset to sunrise lighting switch arduino managed high sensitive ldr based power saver for street light control system etc.

20 led running light circuit.
8 simple touch switch circuit projects.
This switch type is widely popular.
When light intensity high on ldr the resistance through it decrease and when light intensity is low on ldr then the resistance through it will increase and go very high.
The light sensor circuit is a simple electrical circuit which can be used to control the switch on and off electrical load appliances like lights fans coolers air conditioners street lights etc automatically.
