The dark sensor circuit is very useful to automatic switch on and off any appliance by detection of light and dark.
Light sensor on off switch circuit.
Just use your finger to touch them only also can turn on off circuit.
Dark light activated circuit using ldr.
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.
A simple touch on and off switch circuit.
We will experiment with the digital touch switch circuit using jk flip flop as rs flip flop.
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.
This switch type is widely popular.
Get it as soon as thu oct 1.
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.
8 simple touch switch circuit projects.
By using this light sensor circuit we can eliminate manual switching as the loads can be controlled automatically based on the daylight intensity.
