Mini Basic PIR Sensor - BS412

Overview

Imagine a sensor that can detect movement – whether it's your pet, a person, or even something a bit more unconventional like a zombie (though that's not a guarantee). Well, that's what this PIR sensor is all about! It's a little sensor with a big job.

What sets it apart is its small size. Most PIR sensors are bulkier, but this one is compact, making it perfect for projects where you don't want a big, noticeable sensor. Plus, it's super easy to use – all you need is a power source, a ground connection, and a resistor to tweak the delay time. You can attach it to a breadboard or perfboard without any trouble.
