- Module Instructions
A photosensitive resistor module most sensitive to environmental light, generally used to detect the brightness of ambient light, triggering microcontroller or relay module;
2, the module when the ambient light levels reach the set threshold, DO-side output high when the ambient light level exceeds the set threshold, DO terminal output low;
3, DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes;
4, DO OUR outputs can directly drive the relay module, which can be composed of a light control switch.
