Photosensitive Resistance Sensor Module

This is a photosensitive resistance module sensitive to ambient light, commonly used for detecting the immediate environment for the brightness of the light, or MCU trigger or relay, etc. Output port can be directly connected to the single-chip microcomputer, through the single-chip microcomputer for detecting level up and down, so the change in intensity of the light of the test environment. End of output can directly drive the relay module, which can form a light switch – operated.
