4. Three topologies for capacitive sensors: proximity sensor using a finger as the ground plate (a), liquid-level sensing with parallel sensor and ground (b), and material detection and analysis (c).

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Fuel management and environmental systems technology provider Veeder-Root adds Liquid Level Measuring Sensors to its portfolio. They offer simple detection and remote monitoring in aboveground ...

To meet these needs, Sensirion launched the SLD3x platform—a series of digital liquid flow sensors to combine flow measurement, miniature size, and compatibility with several therapies.

Apple says this sensor could include a liquid volume, as well as a pressure-sensing device configured to detect blood pressure. Get daily insight, inspiration and deals in your inbox.
