Module Instructions:
 
1. The photo-resistor module is most sensitive to ambient light and is generally used to detect the brightness of ambient light, triggering a microcontroller or relay module, etc.
2. When the ambient light brightness of the module does not reach the set threshold, the DO output is high. When the ambient light brightness exceeds the set threshold, the DO output is low;
3, DO output can be directly connected with the microcontroller, through the microcontroller to detect high and low, thus detecting the ambient light brightness changes;
4, DO output can directly drive our shop relay module, which can form a light control switch.
5, small board analog output AO can be connected with the AD module, through the AD conversion, you can obtain a more accurate value of the ambient light intensity;
