Description

Photosensitive resistor module most sensitive to the ambient light, typically used to detect the surrounding environment Brightness of light, or mcu trigger relay module, etc; In the module environment, the brightness than the threshold, the altitude yield end when the environmental lighting Intensity set threshold, output low level; Do output can be directly connected to the microcontroller through a single chip microcomputer to detect high and low Level, thus to detect environmental brightness change; Tthe do output can be directly driven our relay module, to form a light-operated switch.
