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 ...

Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, ...

Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far ...
