Dresden, Germany – ZMD AG has added the ZMD31210 cLite IC to its family of capacitive sensor signal conditioning devices. Capacitive sensors offer several benefits, including very low power operation, ...

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 ...

Jon Baldwin of Texas Instruments says this will be easier and lower cost to design when you measure small changes in capacitance in a conductor rather than absolute capacitance levels. Texas ...

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 ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

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 ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

If you do any kind of machining, 3D printing, or PCB layout, you probably have at least considered buying a pair of calipers. Old-fashioned ones had a dial and were mechanical devices, but lately, ...

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 ...

A sensor signal conditioner (SSC) is an integrated circuit that improves — or conditions — the signal coming from a sensor to reduce noise. The SSC also converts the signal from analog to digital ...
