This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained - only needs power and ground, and it's breadboard or perfboard friendly. Usage is super simple: You can power it from 3 to 12V DC, there's an onboard regulator.

HC-SR505 Mini PIR Motion Sensor is based on infrared technology, with automatic control, high sensitivity, high reliability, ultra-small and ultra-low-voltage operation mode. Because of the minimum size and low-power operation mode, it is widely used in various auto-sensing of electrical equipment, especially battery-powered automatic control ...

In this article, we're exploring the world of motion detection using a mini PIR (Passive Infrared) sensor alongside Arduino and Home Assistant. This compact and efficient setup not only adds a layer of interactivity to your projects but also paves the way for a multitude of smart home applications, all triggered by mere movement.

The PIR Mini Sensor’s compact form factor is ideal for small-scale projects, and those where the electronics need to be hidden or protected. The narrow, vertically oriented board can slip through a hole in an enclosure to hide and protect the electronics, leaving only the …
