- This photosensitive module is sensitive to the light, usually used for detecting the ambient brightness and light intensity.
- When there is no light or the light intensity cannot reach the value, DO output is high level. when light intensity over than the value, the module DO output is low level.
- The module digital output DO can be directly connected with the microcontroller, use microcontroller detect high or low level, so that can detect the environmental light intensity change.
- Can use this board digital output DO port drive relay module directly, can also use as a photoelectric switch.
- Application: Light intensity detection, intelligent car light module, with directional, only sense light source in front of the sensor, better to use for searching light.
