Features:
1. Uses a sensitive photosensitive resistance sensor. Light-dependent resistors are widely used to detect light.
2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.
3. Adjustable potentiometer, which can adjust the brightness of the light detection
4. The working voltage is 3.3V-5V
5. Output form: DO digital switching output (0 and 1)
6. With fixed bolt hole, easy to install
7. Small size: 3.2cm x 1.4cm PCB
8. Use a wide voltage LM393 comparator
