In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

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 ...

The Apple iPhone brought the benefits of integrated multi-sensor technology to the masses, and while the application of sensors and their associated algorithms has multiplied and changed the world ...

Capacitive touch switches combine to simulate an analog control. In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in ...

Imagine a bulletproof iPod. It’s possible with new touch sensors that use resonant sound instead of capacitance. • Trapped acoustic resonance is most simply described with an analogy: the ringing of a ...

3D Touch is one of the cornerstone features of the new iPhone 6s and iPhone 6s Plus. But there’s still quiet a bit of mystery as to how Apple implemented this new pressure-sensitive technology in the ...
