Infrared certainly has its uses, but if you’re trying to locate objects, ultrasonic detection is far superior. It’s contact-less, undetectable to the human ear, and it isn’t affected by smoke, dust, ...

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 ...

[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 ...

It's winter ... again ... and time for the all-too-common issue of advanced driver assistance systems (ADAS) proximity-sensor problems, compliments of the seasonal ...

But, similar bursts from other sensors in close proximity may interfere with the echo timing. When that happens, the sensors suffer from a condition called cross talk. Interference from cross talk ...

This one is an unusual smart home project, potentially - how to monitor a fish tank’s health with an AI-enabled ultrasonic sensor system. The detailed project is highlighted on Hackser.io and features ...
