Great Sensors . Having Fun With Electronics Programming!

Description:
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.

Wiring Instructions:
VCC ---- "+"
GND ---- "-"
DO ---- TTL Signal Output
AO ---- Analog Signal Output
