In this tutorial we will use a Passive Infra-Red (PIR) sensor as an input to trigger a LED. A PIR sensor works by detecting heat as an object passes by it. Plug the micro: bit into the GPIO 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 sensors ...

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 ...

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, ...
