Module instruction

1, the photoresistor module is the most sensitive to the ambient light, generally used to detect the brightness of the ambient light, trigger the MCU or relay module;

2. When the ambient light brightness of the module does not reach 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 can be directly connected with the MCU, through the MCU to detect the high and low levels, thus detecting the change of environmental light brightness;

4, DO output can directly drive the store relay module, which can form a light control switch.

Product wiring instructions:

1. VCC is connected to the positive 3.3-5V of the power supply

2. GND connects to the negative electrode of the power supply

3, DO TTL switch signal output

Module usage instructions:

1. The Photoresistor module is most sensitive to the ambient light, which is generally used to detect the brightness of the ambient light, trigger the microcontroller or relay module, etc;

2. When the brightness of the ambient light does not reach the set threshold, the DO terminal outputs a high level. When the brightness of the ambient light exceeds the set threshold, the DO terminal outputs a low level;

3. The DO output terminal can be directly connected to a microcontroller, which detects high and low levels, thereby detecting changes in the brightness of the environment's light;

4. The DO output terminal can directly drive the local relay module, which can form a light controlled switch.
