* Specs
Photoresistors are semiconductor photosensitive devices,
in addition to having high sensitivity, fast response, consistent with the spectral characteristics and value of good features, but at a high temperature, and humidity in harsh environments, but also to maintain
a high degree of stability and reliability, wide pan used cameras, solar garden lights, lawn, detectors, clock, music, cups, gift boxes, mini-Night light, light voice switches, lights automatically switch toys and a variety of light control, light control lighting, lamps and other light automatic opening OFF control field
