[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Vishay’s VCNL4100 is an IR proximity sensor that works up to 1m, and includes an ambient light sensor. Inside, it combines an infra-red (940nm) emitter, photo detectors for proximity and ambient light ...

New Controllers Offer Robust Performance with No System Tuning, Speeding Time-to-Market for White Goods, Home Appliances, Industrial, Medical and Consumer Applications The new CapSense controllers ...

Designing with high-fidelity capacitive proximity sensors requires careful consideration of mechanical design, sensor placement/design, and end-application operating environments. Careful evaluation ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

HomeKit leak sensors offer crucial protection. Learn why detection is a mandatory upgrade for 2026 to prevent costly water ...

The design behind leak sensors is actually pretty cool: essentially, most sensors have two or three metal probes that, when they come in contact with water, detect increased conductivity and set off ...

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 ...
