Oceans comprise about 96.5% of the water-covered surface (71%) of the Earth. Surprisingly, the salinity of these huge bodies ...

This paper proposes a non-destructive multi-channel sensor for liquid level detection based on spoof surface plasmon polaritons (SSPPs). A mathematical model for liquid level sensing is established by ...

However, besides their high price, they also require very high computation capacity. Furthermore, most sensor suppliers provide high-level data, such as object detections, that is complicated to ...

Cable float level switch is the use of plastic injection molding one, so rugged, reliable performance, while non-toxic, corrosion-resistant, easy to install, inexpensive and long-distance multi-point ...

The latter point is important, because there's a notion that beginner cameras are only good for novices. But the best cameras for beginners can take photographs that are every bit as good as any other ...
