The following image shows the circuit diagram for interfacing the Contactless liquid level sensor with Arduino. Connections are pretty simple and only a few wires. Connect the VCC and GND of the ...

Simple Water Level Indicator with Buzzer - Working Principle Here we are using an NPN transistor as a Switch. Initially, there is no voltage applied to the base of the Transistor Q1, and the ...

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 ...

This simple water level indicator will activate an active buzzer (e.g. BeStar BPT-23CX ) in order to make a noise when a certain level of water is being reached. Because the water sensor and the ...

The KOBOLD MM level sensor/transmitter is used for continuous level detection of all types of compatible liquids. It uses the proven float principle with magnetic transmission in a 3-wire ...

We describe and demonstrate a liquid level sensor by parallel connection of two liquid level sensors that consists of single-mode-no-core-single-mode fiber structure followed by a fiber Bragg grating.
