- With a fixed bolt holes for easy installation
- Small PCB board size: 3.2cm x 1.4cm
- Using a wide woking voltage range LM393 comparator
- Application: Light intensity is detected, the light intensity sensor, smart car search light module
Module Instructions:
- Photosensitive resistor module most sensitive to environmental light, generally used to detect the brightness of ambient light, triggering microcontroller or relay module;
- When ambient light intensity does not reach the threshold value, the module DO-side output high when the ambient light level exceeds the set threshold, DO terminal output low;
- DO output can be directly connected to the microcontroller through the microcontroller to detect high and low, thereby detecting the brightness of ambient light changes;
- DO output can directly drive the relay module, which can be composed of a light control switch.
- Analog output and AD module, through AD conversion, can obtain more accurate values of ambient light
Product wiring instructions:
- VCC for positive power supply 3.3-5V
- GND for power supply is negative
- DO TTL switching signal output
- AO analogue signal output
