Good module for the price
Works well but needed some tuning to get the light threshold exactly where I wanted it.

Okay product
Functions as expected but the included instructions were vague regarding wiring.
Q: What size screwdriver is needed to adjust the sensitivity?
A: A small precision flathead screwdriver is required to turn the blue potentiometer.
Q: Is this module compatible with 3.3V logic systems?
A: The module operates best at 5V to 12V. While output might be readable at 3.3V, we recommend 5V for stability.
Q: What is the maximum current the output pin can handle?
A: The output is a signal level only. Please do not connect high current loads directly to the output pin.
Q: Does this provide an analog output signal?
A: No, this specific module provides a digital switching output based on the threshold set by the potentiometer.
Q: Is this sensor waterproof for outdoor use?
A: No, the PCB and components are not waterproof. Please enclose it in a suitable housing for outdoor applications.
