There are plenty of radios you can buy that pick up MW and SW bands if that’s what you’re into. Or, you can follow [mircemk]’s example, and whip one up yourself instead. The build employs an ESP32 as ...

The ESP32 keeps finding new jobs in my house.

This is a maintained version of the original DFRobot_mmWave_Radar library. After more than two years had passed without any commits beyond the initial commit, and issues receiving no attention, I ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

An earlier design introduced a touch solid-state AC switch. The new version advances this concept with a sophisticated human radar sensing system that can also be configured for IoT and smart ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

In recent years, integrating smart home devices into your living space has never been simpler. They have become easier to set up with user-friendly apps and step-by-step guides, and some are ...
