Product Description:

The sensor module has strong adaptability to ambient light. It uses a photoresistor sensor to detect ambient light. When the ambient light brightness of the module does not reach the set threshold, the DO terminal outputs a high level. When the ambient light brightness exceeds the set threshold , DO terminal outputs low level, and the working voltage is 3.3V-5V. The brightness of the sensor can be adjusted by a potentiometer. The photoresistor module is most sensitive to ambient light, and is generally used to detect the brightness of the ambient light, and trigger the single-chip microcomputer or relay module. The DO output terminal can directly drive the relay module of our store, which can form a light control switch.

Product performance:

1. When the brightness of the ambient light does not reach the set threshold, the DO terminal outputs a high level, and when the ambient light brightness exceeds the set threshold, the DO terminal outputs a low level. The detection brightness can be adjusted by a potentiometer. Adjust the potentiometer clockwise to increase the detection brightness; adjust the potentiometer counterclockwise to decrease the detection brightness.

2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.

3. The output port OUT of the sensor module can be directly connected to the IO port of the microcontroller, or it can directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO

4. The module can be powered by a 3.3V-5V DC power supply. When the power is turned on, the red power indicator lights up;

Instructions for use:

1. VCC externally connects 3.3V-5V voltage (can be directly connected to 5v microcontroller or 3.3v microcontroller)

2. GND connects to GND

3. DO digital output interface (0 and 1)
