Module usage instructions:
1. The photoresistor module is most sensitive to ambient light and is generally used to detect the brightness of the ambient light and trigger the microcontroller or relay module;

2. When the ambient light brightness does not reach the set threshold, the DO end outputs a high level. When the ambient light brightness exceeds the set threshold, the DO end outputs a low level;

3. The DO output end can be directly connected to the microcontroller, and the high and low levels are detected by the microcontroller to detect the change in the ambient light brightness;

4. The DO output end can directly drive the relay module of our store, thereby forming a light-controlled switch.

5. The analog output AO of the small board can be connected to the AD module. Through AD conversion, a more accurate value of the ambient light intensity can be obtained.

Application:
Light brightness detection, light brightness sensor, smart car light-seeking module.
