Module instructions

1. The photoresistor module is the most sensitive to ambient light, and is generally used to detect the brightness of the ambient light, trigger the single-chip microcomputer or relay module, etc.;

2. When the module’s ambient light brightness does not reach the set threshold, the DO terminal outputs a high level; when the external ambient light brightness exceeds the set threshold, the DO terminal outputs a low level;

3. The DO output terminal can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the change of the light brightness of the environment;

4. The DO output terminal can directly drive our relay module, which can form a light control switch.

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