Photoresistor Sensor Module

The BIT‑TREE photoresistor module adopts a high‑precision photoresistor as the sensing element. It operates on 3.3V‑5V wide supply voltage, delivering dual output modes: analog signal (A0) and digital switching signal (D0). An onboard potentiometer tunes detection sensitivity to gauge ambient light intensity accurately. It fits light‑activated switch development, brightness monitoring, smart lighting control, maker education and related DIY projects.
