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 ...

Researchers from Morocco, the UAE, Egypt, Italy, and South Africa have developed a low-cost IoT- and fuzzy logic–based irrigation system that dynamically adjusts watering using real-time soil and ...

In this paper, we investigate the design of a water level sensor device that is able to detect and control the level of water in a certain water tank or a similar water storage system. The system ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.
