A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Proximity sensors are common enough in automation projects that we hardly give them a second thought — pick something with specs that match the job and move on. But they can be fussy to get adjusted ...

When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

Once you have a track and a kart to race on it, what’s missing? A lap counter that can give your lap times in hardcopy, obviously! That’s what led [the_anykey] to create the Arduino-based Lap Timer to ...

Advanced sensor technologies like gunshot detection, vape sensors, aggression detection, environmental monitors, AI visual recognition, and occupancy sensors are increasingly being integrated into ...

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 ...
