It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Research on a new sensing device able to simultaneously identify more than 3,000 biological materials shows great promise, says one of its developers, Ravi Saraf of Virginia Tech’s chemical ...

As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it’s his ...

This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.

Engineered with a polarization filter that allows only light received from a specially designed reflector to be recognized by the detector, the Series OPDM 12 retro-reflective laser sensors eliminate ...
