The PIR module actually consists of a pyroelectric sensor (looks like an old metal transistor with a black window on the top), which generates energy when exposed to heat, and it’s tied in closely ...

The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes from Sparkfun. The difference between the two is important to note: The Sparkfun PIR has ...

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Camera’s using PIR motion detection usually allow you to adjust the sensitivity level within the companion app, so that more- or less-pronounced motion triggers the sensor.

With just a Wemos D1 Mini, a standard PIR sensor, and some open source code, you can create a practical self-contained motion sensor module that can be placed anywhere you want to keep an eye on.
