Module instructions
1.The photoresistor module is most sensitive to ambient light, generally used to detect the brightness
of the surrounding environment, triggering a single-chip or relay module;
2. When the brightness of the ambient light reaches 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 terminal can be directly connected to the single-chip microcomputer, and the high-low level
is 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 the relay module of the store, which can form a light control switch.
