The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

There are many types of contactless sensors available in the market, including capacitive sensors, ultrasonic sensors, radar sensors and optical sensors. In this article, we are going to look at a ...

Fig. 2: Circuit diagram of the capacitive touch keyboard The sensor setup includes a medium to high-value resistor, some jumper wires, a small piece of aluminum foil. You can use any resistor value ...

Learn how to use a capacitive sensor and an Arduino to measure and display the level of liquid in a container. Follow the steps to make, calibrate, and test the circuit.

This project started as an experiment to see if a water level sensor (with fixed intervals) could be built, using the Arduino ADCTouch library and capacitive sensors. Capacitive sensors have the ...

He’s calling the effect “Capacitive turbulence”, and he’s open to suggestions as to its mechanism. He can only make it work on the Arduino, other boards with ADCs don’t cut it.

This paper presents a measurement system with capacitive sensor connected to an open-source electronic platform Arduino Uno. A simple code was modified in the project, which ensures that the platform ...

The sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder.
