Gravity: Digital PIR (Motion) Sensor
Digital PIR motion sensor for Arduino and Raspberry Pi. Detects infrared radiation changes for motion detection and home automation.
Digital PIR motion sensor for Arduino and Raspberry Pi. Detects infrared radiation changes for motion detection and home automation.
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.
Module supply input for the Gravity digital PIR motion sensor.
Ground reference for module power and digital output.
