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 ...

Ever wondered how a touch-sensitive screen works? The answer is capacitive sensing, which can detect the presence of your finger through the protective glass sheet and doesn't require any pressure.

In Part 1 of this article, we explained popular liquid-level sensing methods and their limitations. We also delved into why capacitive-sensing techniques are superior to traditional methods used for ...

Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a bunch of ways to go about it, and this capacitive ...

Capacitive touchscreen devices have always been a hassle when it's cold and you're wearing gloves. Many phones have trouble picking up any input from anything that is not skin to screen. However, late ...

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 ...

Apple on Tuesday was awarded a patent that, if recent rumors are to be believed, might make its way into next year's iPhone model. Specifically, the company now owns IP covering a fingerprint sensor ...
