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 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 ...

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.
