The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. ... PIR Pin “out” connects to Arduino Digital 2. Here is the Arduino code for the Parallax sensor.

The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects something. Note that after powering the PIR sensor module, it needs about 10 to 60 ...

when it detects a moving target. Most Digital PIR sensor modules have three connector pins: Vcc (5V), Ground (0V), and Output. The output is a digital LOW or HIGH, depending on whether the sensor has ...
