Abstract
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.
