light sensor
Illumination measuring device
A light sensor is a device that detects the presence or intensity of light and converts it to an electrical signal.
Cameras use light sensors to capture images; phones use them to adjust screen brightness automatically.
Motion-activated lights often combine light sensors with motion detectors to operate only after dark.
