Module Description
Photoresistor module is the most sensitive to ambient light, generally used for testing
Ambient light brightness triggers microcontroller or relay module;
When the ambient light intensity does not reach the threshold, the module DO side output high
, Ambient light level exceeds the set threshold, DO terminal output low;
DO output can be directly connected to the microcontroller through the microcontroller to detect
High and low, thus detecting changes in ambient light brightness;
DO output can directly drive the relay module, which can be composed of light control switch.
