The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

Object motion can be tracked using techniques, including ultrasonic waves, infrared waves, and microwaves. In this article, the applications of infrared motion sensors are discussed. The use of motion ...

The power switch with infrared proximity sensor is intended for the recognition of obstructions at distances of a few millimetres to a few centimetres. This compact sensor switch can be used to open a ...

Rename the sample-config.json to config.json and integrate your sensor in the accessories array. The pins of the Raspberry Pi require root rights to control them. Therefore you have to save your ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

The motion sensor switch circuit can automatically turn on a water sprinkler but you can easily use it as a motion sensor light switch or motion activated alarm too. Before beginning the construction ...

What is a Motion Sensor? A motion sensor (or motion detector) is an electronic device that is designed to detect and measure movement. Motion sensors are used primarily in home and business security ...
