Makers and hobbyists that are looking for a capacitive touch sensor for a project, might be interested in a new touch sensor board called the EasyTouch. The EasyTouch capacitive touch sensor can be ...

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 ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

Now that we have discussed the theory about the sigma-delta modulator, let us design a simple proximity sensor that will detect an approaching hand and switch on an LED. A 0.5 mm 2 wire, 10 cm long, ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

A lot of consumer gadgets use touch sensors now. It is a cheap and reliable way to replace a variety of knobs and switches on everything from headphones to automobiles. However, creating a custom ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices, ...
