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 ambient light brightness;
4. The DO output terminal can directly drive our relay module, which can form a light control switch.
Product wiring instructions:
1. Connect VCC to the positive pole of the power supply 3.3-5V
2. GND connects to the negative pole of the power supply
3. DO TTL switch signal output
