[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great so he ...

A sensor that can detect the water in a beaker, container or tank from outside based on capacitance measurement. Detection of Water overflow in a tank is one of the main topics when it comes to energy ...

As with traditional mechanical switches, a user's interface experience with a capacitive sensor is directly related to the way the sensor responds (sensitivity) upon contact under all operating ...

Candle clocks were once an easy way to build a clock without using complex mechanical devices: just observe how quickly a thin candle burns down, mark an identical candle with periodic gradations, and ...

This project demonstrates a simple water detection system using an Arduino board and a water sensor. The system uses an LED to indicate whether water is detected. The LED turns ON when no water is ...
