A multi-point liquid level sensor was proposed in this letter, which is based on a plastic optical fiber with a race-track helical structure. The principle of liquid sensing is based on higher modes ...

PH4502C Sensor Arduino Library This Arduino library provides a convenient and easy-to-use interface for the PH4502C sensor, allowing you to effortlessly integrate it into your Arduino projects. The ...

This is a library for the Arduino IDE that helps interface with ST's VL53L0X time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

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.
