5Pcs Digital Light Intensity Sensor Module Photoresistor Photoresistor for Arduino UNO

The most sensitive ambient light photoresistor module, commonly used to detect ambient light levels and trigger microcontroller or relay modules; the comparator output signal is clean, with a good waveform, drive capability, and a current rating of over 15mA. Output type: DO (0 and 1) digital switching outputs and AO analog voltage output. Includes fixed bolts for easy installation and an adjustable potentiometer to adjust the light detection brightness. Features: 1. Sensitive photoresistor sensor type. 2. The comparator output signal is clean, with a good waveform, drive capability, and a current rating of over 15mA. 3. Adjustable potentiometer for adjusting the brightness of the light detection. 4. Working voltage: 3.3V-5V. 5. Output format: digital switching outputs (0 and 1). 6. Fixed bolt hole for easy installation. 7. PCB size: 3.2cm x 1.4cm. 8. LM393 wide voltage comparator module. Applications: 1. Photosensitive resistor module, highly sensitive to ambient light, generally used to detect ambient light brightness and trigger microcontroller or relay modules; 2. When the ambient light brightness does not reach the set threshold, the DO-side output is high; when the ambient light level exceeds the set threshold, the DO-side output is low; 3. The DO output can be directly connected to the microcontroller to detect high and low ambient light levels, thus detecting changes in ambient light brightness. 4. The DO output of the relay module can directly drive the store, which can consist of a light control switch. Includes: 5x Light Sensor
