I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

This system continuously monitors liquid presence at three key points in a tank (e.g., low, high, and an overall check point) using XKC-Y25-V non-contact capacitive sensors. An ESP32 (specifically, a ...

Designed by Everything Smart Home, the Everything Presence Lite is a compact, ESP32-based mmWave presence sensor designed to be easily integrated with Home Assistant open-source home automation ...

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 ...

For smart home deployments, there are a lot of ways to track the presence of individuals in a room. There are motion detection sensors that use mmWave and PIR, and you can also use simple detection ...

The ESP8266 and its heavyweight sibling the ESP32 are fantastic boards to develop with as they allow you to quickly and easily get a project online. Just tack a few sensors and some LEDs on them, and ...
