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 ...

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 ...

Using a PIR sensor, trigger a LIFX bulb controlled via local wifi network. PIR sensor will stay on for 35 seconds by default but this could be easily extended/reduced. A more detailed write-up can be ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

The main aim of this mini-project is to demonstrate the working of a PIR motion-based light bulbs. This is to mainly minimize energy consumption and save electricity bills. Sometimes people forget to ...

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 ...

Aqara introduces the FP300 Presence Multi-Sensor with dual PIR and mmWave technology, offering up to a three-year battery ...
