Use

1. The photodiode module detects ambient brightness very sensitively, ideal for monitoring surrounding light intensity.
2. The DO output port goes high when light conditions are low or light intensity is below the set threshold; it goes low when light intensity exceeds the threshold.
3. The digital output D0 can be directly connected to a microcontroller to detect high and low levels and monitor variations in light intensity.
4. The digital output can also directly drive a relay module to automate actions based on light detection.

Package included

• 1 light sensor module
