Perfect Arduino match
Plug and play with my Uno board. The pinout is standard and the example code found online works immediately.

Needs calibration
Had to spend time adjusting the threshold for digital output. It works but expect to tweak settings for your specific environment.

Great for automation
Used this for a smart lamp project and it works flawlessly. The analog output gives nice granular data for adjusting brightness levels.

Good but sensitive
Works well however the sensitivity potentiometer is quite touchy. Took some time to calibrate exactly where I wanted it.
Q: Does this module support 3.3V logic levels?
A: Yes, the module operates comfortably between 3.3V and 5V, making it suitable for both Arduino and ESP32 projects.
Q: What is the maximum cable length for the sensor?
A: We recommend keeping connection wires under 50cm to prevent signal noise and voltage drop issues.
Q: Do I need a specific library to use this?
A: No specific library is required. You can read the analog pin using standard analogRead functions in the Arduino IDE.
Q: Is this sensor waterproof for outdoor use?
A: No, this module is not waterproof. It is designed for indoor use or must be housed in a protective enclosure for outdoors.
Q: Is the output analog, digital, or both?
A: This module provides both Analog (AO) for continuous light levels and Digital (DO) for threshold switching.
