Moderately priced Passive Infrared PIR Sensor modules are now widely available. By using these readymade and pre-configured PIR sensors, even an average electronics hobbyist can construct his/her own ...

This IR motion sensor relay switch circuit is designed for use with all kinds of medium-power automobile/domestic 12V DC loads. It is a simple solid-state relay (SSR) switch, controlled by a standard ...

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 ...

We’ve previously shown how to control lights with a 433 MHz PIR motion sensor via a 433MHz to WiFi bridge based on an ESP8266 WiFi module itself commanding Sonoff Basic wireless switches connected to ...

Living objects with a body temperature above 0°C emit heat as infrared radiation, also known as thermal radiation, which is invisible to the human eye. PIR sensors, designed for this purpose, can ...

This project is an example of a PIR motion sensor for the Philips Hue bridge. The sensor can be registered at the Hue bridge as an IP sensor to control lights connected to the hue bridge. The sensor ...
