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 ...

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 ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

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 ...

SU, UK, UT and TU series round body and UQ series cubic plastic ultrasonic distance sensors from AutomationDirect are now available in sensing distance ranges from 60mm to 8000mm, in metal or plastic ...
