Photosensitive Resistance Sensor Module Light Sensor LDR Sensor For Arduino

The photosensitive resistance module has the most sensitive ambient light, generally used for detecting the environment immediate of the brightness of the module light, triggering SMC or relay, etc.

The brightness of the ambient light module can not reach the threshold of setting, DO exit end of high-level, when light brightness of the external environment of the development of threshold, only to stop output low level.

The output port can be directly connected to the single-chip microcomputer, through a single-chip microcomputer for detecting levels up and down, so the change in intensity of the light of the test environment.

The end of the output can directly drive the relay module, which can form a light switch–operated.
