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.

5 FAQ
