Layers of silicone are sandwiched between two lengths of silver-plated conductive fabric forming — by some approximation — a capacitance sensor. While the total surface area doesn’t change ...

But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely. He also shows, with a short ...

Three years ago, Biogen published a method, using capacitance sensors from Aber Instruments, for correlating “online” (also known as inline) capacitance VCC values with much easier-to-obtain ...

The duration (T+) of the positive oscillation half-cycle (pin 13 high) is controlled by R2C2, while R1t (the trimmer’s top half) and Cx (humidity-sensor capacitance) control the duration (T-) of the ...

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 detect absolute pressure.

ADI also offers a library of sensor sizes, so manufacturers can customize the shape of capacitance sensors to differentiate their products. In a capacitive touchpad design, sensors consist of ...

Created by ATLab of South Korea, the company is distributing the FMA1127 touch sensor controller that converts capacitance generated by the human body and conductive touch pad to digital data with ...
