This is a small rebuild of an existing native Android application produced by myself of the same nature. My main goal of this project was to learn more about the Flutter framework and to bring some UI ...

Laser Proximity Sensors use laser beams to detect the presence or absence of objects within a certain range. They are used in security systems, robotics, automation, and industrial processes, where ...

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 ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Starrycom Sensing Technologies, a US technology startup, has announced the release of its SPX-1 smart proximity sensor IC product. The IC is now available for sampling. For decades, proximity sensor ...

In this example I connected it to a water meter. When starting this sketch for the first time, it will show up as a new WiFi access point where you need to connect to Once connected, configure the ...
