Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites ... The code is an Arduino project for the Digispark Attiny85 to turn on a light source ...

One advantage of using Arduino as a security system is the flexibility ... The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion of ...

This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes ...

The ICU-Duino motion sensor Arduino Shield has been designed to provide ... human presence through the use of a passive Infra-red (PIR) sensor from all directions. In addition, this shield ...

[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 ...

When everything’s plugged in, this is how your Arduino, motion sensor ... as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino.

Like the Arduino and Raspberry ... 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 ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal.
