Great Sensors for Smart Car Arduino Project. Having Fun With Electronics and Programming!
Photodiode module is most sensitive to environmental light intensity , generally used for detecting the ambient brightness and light intensity.
Compared with Photosensitive Resistance Sensor, this module has better directionality, can sense light in a certain direction.
When ambient light intensity does not reach the threshold value, the module DO port output high lever; when the ambient light intensity exceeds a set threshold, the D0 output low lever.
Sensitivity Adjustable. Increases detection brightness by adjusting the potentiometer clockwise and decreases by adjusting the potentiometer counterclockwise.
