Working voltage: 3.3V~12V
- Current: Over 15mA
- Output: Digit switch output (0, 1)
- Uses wide voltage LM393 comparator
- Indicator light for indicating switch and power.
- Using photoconductive resistance sensor
- Sensitive to light, it's often used to test light brightness around
- Universal use with photo resistor sensor module
- When environment light brightness can't reach the set range, the output is high; when it over the set range, the output is low
- Directly connected to microcontroller, testing environment light brightness
- Drive relay module directly via output port, which can be composed of a light control switch
