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 ...

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.

In Texas — at least around Houston — we don’t have basements. We do, however, have bilges. Both of these are subject to taking on water when no one is paying attention. A friend of mine asked me what ...

Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far ...

To beat cancer, early detection is crucial. Now, a team of Japanese and American scientists has revealed extremely thin sensors that could one day be built into skin-tight, tumor-detecting gloves for ...
