Light Sensor On Off Switch Circuit

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 dark sensor circuit is very useful to automatic switch on and off any appliance by detection of light and dark. This switch type is widely popular.
