Abstract

In some examples, a method of sensor degradation compensation is described. The method may include generating first characterization data for calibration of a first sensor, from amongst multiple sensors that include the first sensor and at least a second sensor, based on first sensor data generated by the first sensor. The method may further include providing the first characterization data to be pushed to the second sensor. The second sensor may be configured to be calibrated with the first characterization data. The method may also include collecting second sensor data generated by the first sensor and generating second characterization data based on the second sensor data after the first characterization data is provided. The method may further include providing the second characterization data to be pushed to the second sensor. The second sensor may be configured to be recalibrated with the second characterization data.
