SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level ...

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

Use an Arduino Mega to measure the level of a liquid by means of a 4-20mA submersible pressure transducer. By connecting a resistor in series with the transducer, the voltage across the resistor can ...

This project demonstrates a water level monitoring system using an ultrasonic sensor and an Arduino. The system measures the water level in a container based on input voltage and displays the height ...

Researchers at Yokohama National University have created a liquid-based tilt sensor that only needs simple interface electronics – some 10MΩ resistors and a Microchip ATmega microcontroller in the ...

High-resolution monitoring of liquid levels over a wide range has always been a great challenge. In this article, a fiber ring laser (FRL) sensor system with Fabry-Perot interferometer (FPI) is ...

In order to diagnose the state of the liquid level sensor on the tank truck and make sure the wireless sensor networks (WSN) work properly, this paper studies an on-line self fault diagnosing method ...
