Pinout

  • DGravity PH2.0-3 signal pin

    Digital motion output from the SEN0171 PIR sensor; DFRobot example wiring connects this output to Arduino digital pin 2, and the result text says it outputs about 3V high when motion is detected and 0V otherwise.

Light and colour

Photoresistors and color sensors both respond to light, but they expose very different signals and are not sensible drop-in substitutes.
