Water-leak sensors, which keep you in the loop if your plumbing fixtures spring a leak, can prevent a small spill from becoming a big problem.

Possibly the most used household fixture, and one we usually take for granted, the toilet is a marvel of engineering simplicity. Even typical modern toilets still employ just a couple basic mechanical ...

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 ...

In this work, we propose a robust water level sensor based on a fiber Bragg grating (FBG). The sensor head is formed by a cylindrical PVC cap with 4 cm diameter. The cap was filled with silicone ...

We demonstrated a high-sensitivity liquid level sensor based on the balloon-shaped fiber Mach-Zehnder interferometer (MZI). To make an optical fiber MZI sensor, a bare single mode fiber (SMF) is bent ...
