  • This product is a photo sensitive resistance which which could work as a light tracking module for small cars. The photosensitive resistance is extremelly sensitive to the ambient light and is able to trigger the relay module. The DO output can attach to the single chip micro computer directally and detect higher or lower power through the microcomputer. It can also connect to the relay module and form a light-operated switch.
