As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...

Try to make a kind of mixed-signal sound generator, a bit like a classic Theremin, but with two of these modern, digital ToF sensors (one for pitch and one for volume) paired with an XR2206 analog ...

Smart Home Node Project with ESP32-PoE This project develops a compact, PoE-powered smart home node based on the Olimex ESP32-PoE-EA-16MB-WROVER, designed to manage a 2.4 GHz mesh network, ...

Analog pH sensors output a small analog voltage signal, generally in the millivolt range, that corresponds linearly to the pH value. This voltage signal is continuous and varies smoothly as the pH ...

Prometheus has been awarded a U.S. patent for a new technology that encrypts and authenticates legacy analog security systems ...

There are already many cheap ESP32 drones on AliExpress, or you can even make an ESP32 DIY drone for about $12, but ...

Cooking is all about temperature control: too cold isn’t good enough, and too hot can ruin everything. To aid in this regard, [Printerforge] created a smart temperature alarm to keep them awa… ...

The act of turning on your PC is a simple one, but pressing the power button isn't the only way to do it. In fact, I would argue the power button is archaic, and there are significantly more ...

Metal oxide semiconductor-based sensors are promising for hydrogen detection but their detection speed and selectivity are still limited. Here, a hydrogen sensor consisting of palladium single ...
