In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...

Liquid-level sensing based on capacitive sensors comes with its own challenges. It’s like absolute capacitance sensing. Unlike touch detection, the absolute value of the liquid level needs to be ...

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 ...

AMS has announced a configurable capacitive sensing front end which allows speed and resolution to be traded to optimise designs. Called PCap04, it can capture and digitise 50,000 times per second at ...

Zac has been writing about Android as a hobby since he was a teenager and fulfilled his ambition of doing so professionally when he joined Android Police as a Reviewer in 2020. Zac specializes in ...

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...
