Two complementary sensor technologies will be discussed in detail in this chapter: capacitive electric field based, and inductive (eddy current) electromagnetic field based. Figure 8.1.1: Noncontact ...

Happily there is a solution in the form of capacitive sensor probes, and it is these that [Electrobob] is incorporating in to a home automation system. Unfortunately the commercial capacitive ...

Frequency The output signal is encoded via amplitude modulation (AM), frequency modulation (FM), or some other modulation scheme, but the signal is still analog in nature ... 2-Wire 2-Wire DC ...

Capacitive sensing libraries for the Arduino ... and the radial touch sensor will emulate the ‘wheel’ interface on an iPod. Very cool stuff, and we can’t wait to see these in a few more ...
