[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 sensors ...

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 ...

Passive Infrared Sensor (PIR) is very useful module, used to build many kinds of Security Alarm Systems and Motion Detectors. It is called passive because it receives infrared, not emits. Basically ...

Los sensores PIR le permiten detectar movimiento, casi siempre se usan para detectar si un humano se ha movido dentro o fuera del alcance de los sensores. Son pequeños, económicos, de bajo consumo, ...

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 ...

Abstract: In this paper, we use a modified passive infrared radiation or pyroelectric infrared (PIR) sensor to classify 5 different human motion events with one additional “no action” event. Event ...
