A method, apparatus and system of capacitive sensor based inventory control is disclosed. In one embodiment, an inventory management system includes a first conductive surface and a second conductive surface substantially parallel to the first conductive surface, a sensor to generate a measurement based on a change in a distance between the first conductive surface and the second conductive surface, a scale formed with a set of plates having inserted between the set of plates the first conductive surface and the second conductive surface and a container placed above the scale such that an item (e.g., a liquid, a solid, a discrete part, a powder and/or a gas, etc.) of the container is weighed through the measurement. The inventory management system may further include a reference capacitor associated with the apparatus to enable the sensor to adjust the measurement based on the environmental condition.

Capacitive sensor based inventory control

A capacitive device and method with an enhanced measurement error correction capability is disclosed. In one embodiment, an apparatus includes a sensor capacitor based on one or more pairs of parallel conductor surfaces, a housing to encompass the sensor capacitor, a digitizer module in the housing to generate a digital measurement based on a change in a capacitance of the sensor capacitor when a contact zone of the housing is deflected by a force applied on the contact zone. The apparatus also includes a compensation module of the digitizer module to apply another digital measurement of one or more distortion factors to the digital measurement to minimize an effect of the one or more distortion factors to the apparatus. In addition, the apparatus includes a communication module to communicate an analog signal and/or a digital signal through a wired channel and/or a wireless channel.
