How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source ...

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 ...

Abstract: This article presents a humidity sensor based on a micro-porous metal-organic framework (MOF) KAUST-7. A series of sensing-test experiments were performed and the results demonstrated that ...

Abstract: This work demonstrates a deep learning–assisted microbottle resonator (MBR) humidity sensor coated with agarose and coupled to a tapered fiber. The convolutional neural network (CNN) ...

I wanted to build a sensor to determine the state of my garage door—open or closed—and send that state to Home Assistant so I can display the status in a dashboard and build automation from it (e.g.
