TECHNOLOGIES FOR PREDICTIVE MONITORING OF A CHARACTERISTIC OF A SYSTEM
First Claim

1. A predictive sensor module to monitor a characteristic of a monitored system, the predictive sensor module comprising:
- a primary sensor to produce primary sensor data indicative of a primary characteristic of the monitored system;
one or more secondary sensors to produce secondary sensor data indicative of a secondary characteristic, different from the primary characteristic, of the monitored system; and
a sensor controller to (i) determine a measured value of the primary characteristic based on the primary sensor data, (ii) determine a measured value of the secondary characteristic based on the secondary sensor data, (iii) predict a predicted value of the primary characteristic using a predictive model with the measured value of the secondary characteristic as an input to the predictive model, and (iv) determine whether to update the predicted model based on a comparison of the measured value and the predicted value of the primary characteristic.

Abstract
Technologies for monitoring a characteristic of a monitored system include determining a measured value of the primary characteristic of the monitored system sensed by a primary sensor and a measured value of the secondary characteristic of the monitored system sensed by a secondary sensor, and predicating a predicted value of the primary characteristic based on the measured value of the secondary characteristic. The measured and predicted values of the primary characteristic are used to determine whether the primary sensor is properly functioning.
