This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively insensitive to ambient light, it uses a ...

This document describes a schematic for hand and break-a-beam detection based on the MLX75303 Optical Switch SensorEyeC. Hand Detection is gaining popularity in a lot of consumer applications like ...

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 ...
