Works for the Arduino
Great. Everything for the Arduino on Amazon!😁😄

Compatible with 3.3v GPIO
Works well and consistently, and the sensitivity adjustment is easy to set. The output will go low when it sees light, as high as Vcc when it senses dark. If you supply 5v, it will output 5v. The output seems to have a high output impedance, so using a simple voltage divider resistor network to bring the output down to 3.3v is a bit problematic if using anything under 100k ohm resistors. Just measure the output to make sure. However, if you supply 3.3v for the Vcc, the output will go to 3.3v, which is compatible with most GPIOs (like the RP2040 uC). So no need for any kind of level shifting or voltage divider resistors. It uses VERY little current, so can be supplied by the 3.3v output of many uC boards.

Works With 3V3 and 5V
Great product for use with my ESP32, Arduino, and Raspi projects! These boards are of a sturdy build, and they are capable of working with both3V3 and 5V logic levels...even with 20+ feet of wire running between the boards!

Work as described.
I used them to switch on and off crossing lights on my model train layout. Work as they should.

Cost effective pre-built sensor
I was looking to build a CDS sensor to allow an easy non-intrusive system to show me an indicator LED on an oxygen machine to give a remote status. This worked perfectly, inexpensive and save me a lot of time in filling this need. Amazing what you can find on Amazon!
