Abstract
A mechanism is provided to field adjust offset values for packaged sensors incorporated in devices. Embodiments provide for a processor in the sensor package to measure current environmental conditions and set a zero offset for the sensors in the package in light of those current environmental conditions. In this manner, any changes in the sensor over the sensor's lifetime and current environmental conditions that can affect functioning of the sensor can be accounted for in operational measurements taken by the device.
