The ISL29147 is a low power Ambient Light Sensor (ALS) and proximity (PROX) sensor. It has a built-in IR-LED for the proximity function. The ALS function measures the amount of light (in the visible ...

STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm passive IR sensor. This provides more accurate results as well as information about the distance rather than just a basic ...

Also at the show, Astyx Inc. (formerly known as Microwave Technology and Sensors) showed a proximity sensor that detects the distance of near-field (about half an inch) targets, including carbon fiber ...
