A capacitive sensing evaluation kit from Cypress Semiconductor is being made available free to design engineers by distributor Future Electronics on its ‘My Board Club’ website. The CY3280-MBR3 ...

Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

[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 ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

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 ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...
