A team from the Northeastern University has developed a sensor that requires almost no power to work and operate. Made for the US Department of Defense's Darpa (Defense Advanced Research Projects ...

Abstract: This study presents a novel closed-loop micro-electromechanical system infrared sensor that features dual-membranes, mitigating drift caused by the outgassing induced pressure change from ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The built-in web server, which is hosted on the ESP32, allows monitoring through any device connected to the local network, ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...
