Capacitance Sensor Guide (AD7746) July 18, 2009 by Eliot 20 Comments [Marcus] has written up his experiences using the AD7746 capacitance sensor .

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great s… ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

Comparison of Capacitive with Induction Sensors. Capacitive sensing involves charging up plates, so it is somewhat slower than inductive: 10 to 50 Hz, with a sensing distance from 3 to 60 mm.

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 ...

This says that ALL 50 Ohm transmission lines in FR4 have exactly the same capacitance per length. If we make the line width wider, we have to make the dielectric thicker to preserve the 50 Ohms, and ...

At 50% RH, the capacitance of the sensor is typically 100 to 500 pF. The change in capacitance is directly proportional to the change in humidity, typically 0.2 to 0.5 pF for every 1% change.

Spoiler summary: When the capacitance (in femtofarads) of your discontinuity is greater than 10 × risetime (in ps), the discontinuity will affect the signal. Remember: before you start using rules of ...

August 2, 2007 Alps Electric has completed development of the industry’s smallest (4.8mm long x 4.8mm wide x 1.8 mm high) capacitance type pressure sensor to ...

Capacitive sensors are able to detect when they are touched without requiring a pressure or movement. Even with AirPods Pro, it's possible to knock them out of your ear so anything that stops you ...
