Abstract

Sensor accuracy issues may arise when a humidity sensor is kept in a high humidity environment for an extended period of time. In these circumstances, a humidity sensor reading may tend to may become less accurate over time. To improve the accuracy of sensor readings, methods and systems described herein estimate and correct for sensor drift in high humidity conditions. Methods and systems described herein may use memory to store past humidity or other sensor readings so that an estimated amount of sensor drift may be determined to improve the accuracy of sensor readings. A memory may be embedded in a sensor module so that past readings for a given sensor module are stored in the memory of the sensor module. Algorithms for sensor drift compensation, and systems and methods that use such algorithms to improve the accuracy of sensor readings, are disclosed herein.
