Resources and Going Further
For more information on the PIR sensor, the PIR motion sensor datasheet may provide some insight.
Now that you've got your Arduino hooked up to a PIR sensor what motion-detecting project are you going to create? Need some inspiration? Check out some of these related tutorials using the PIR motion sensor:
Photon Remote Water Level Sensor
Learn how to build a remote water level sensor for a water storage tank and how to automate a pump based off the readings!

Qwiic GRID-Eye Infrared Array (AMG88xx) Hookup Guide
The Panasonic GRID-Eye (AMG88xx) 8x8 thermopile array serves as a functional low-resolution infrared camera. This means you have a square array of 64 pixels each capable of independent temperature detection. It’s like having thermal camera (or Predator’s vision), just in really low resolution.
