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 ...

The term passive refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. It works entirely by detecting the energy given off by other objects.The D204B PIR ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sens… ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada ...
