Module instructions
1. The photosensitive resistor module is sensitive to the ambient light ZUI, which is generally used to detect the brightness of the ambient light and trigger the single-chip microcomputer or relay module;
2. When the ambient light brightness of the module does not reach the set threshold, the DO output is high. When the ambient light brightness exceeds the set threshold, the DO output is low;
3, DO output can be directly connected with the microcontroller, through the microcontroller to detect high and low, thus detecting the ambient light brightness changes;
4, DO output can directly drive our shop relay module, which can form a light control switch.
5, small board analog output AO and AD module can be connected through AD conversion, you can obtain a more accurate value of the ambient light intensity;
Product wiring instructions:
1, VCC connected to the power supply positive 3.3-5V
2. GND is connected to the negative pole of the power supply
3, DO TTL switch signal output
4, AO analog signal output
