Levels change slowly in tanks that are usually geographically dispersed, making them ideal candidates for wireless sensor networks with minimal impact on control performance. Digital and wireless ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...

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 ...

Abstract: This paper presents an application-specific integrated circuit (ASIC) front-end, to interface the printed capacitive sensors, using an amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) thin film ...

Abstract: This article proposes a nondestructive multichannel sensor for liquid-level detection based on spoof surface plasmon polaritons (SSPPs). A mathematical model for liquid-level sensing is ...
