Module Instructions
1. The photoresistor module is sensitive to ambient light, and is generally used to detect the brightness of the ambient light and trigger the microcontroller or relay module, etc.;
2. When the ambient light brightness of the module does not reach the set threshold, the DO terminal will output a high level, and when the ambient light brightness exceeds the set threshold, the DO terminal will output a low level;
3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high and low levels 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 the relay module of our store, thus forming a light-controlled switch.
5. The analog output AO of the small board can be connected to the AD module, and through AD conversion, a higher value of the ambient light intensity can be obtained;
Product wiring instructions:
1. VCC is connected to the positive pole of the power supply 3.3-5V
2. GND is connected to the negative pole of the power supply
3. DO TTL switch signal output
