While there are loads of impressive and complex projects here on Hackaday, sometimes it’s the simple ones that really speak to us. In this case we were presented with [Isabell Park]’s easy-to-follow ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

The main principle of the circuit is to provide security using PIR sensor. This can be used in the museums to protect the valuable things and also in defense applications to detect the humans in war ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors.

You can use mmWave sensors to monitor presence rather than simply detecting motion.

I love Aqara’s products, and if you love HomeKit, it’s a vendor you’ll want to follow. They make incredibly easy-to-use and reliable smart home products at prices that won’t empty your bank account.

The ultimate goal with any smart home setup is simple. You want your home to work for you instead of you against it. There are plenty of devices that can help to make this happen, but none can help ...
