Abstract
Systems and techniques for determining sensing margins and/or diagnostic information associated with a sensor are presented. A statistics component generates statistical data based on sensor data associated with a sensing device. A margin component generates sensing margins for the sensing device based on the statistical data. An output component generates an indicator for a changing condition associated with the sensing device based on the sensing margins. In an aspect, a diagnostic component generates diagnostic data for the sensing device based on the statistical data.
Claims20
A system, comprising:
- a memory that stores computer executable components;
- a processor that executes computer executable components stored in the memory, wherein the computer executable components comprise:
- a receiving component that receives sensor data from a sensor device, wherein the sensor data comprises sensed values that differs from a threshold value indicating an object monitored by the sensor device is in a defined state;
- a statistics component configured to generate statistical data based on the sensed values representative of the object being in the defined state;
- a margin component configured to generate a sensing margin for the sensor device based on the statistical data, wherein the sensing margin is generated in response to a determination that an average value of the sensed values differs from the threshold value by a defined multiple of a standard deviation;
- and
- an output component that configures the sensor device according to the sensing margin.
A non-transitory computer-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- receiving, from a sensor device, sensor data comprising sensed values that differs from a threshold value indicating an object monitored by the sensor device is in a defined state;
- determining statistical data based on the sensed values representative of the object being in the defined state;
- determining a sensing margin for the sensor device based on the statistical data, wherein the sensing margin is determined in response to a determination that an average value of the sensed values differs from the threshold value by a defined multiple of a standard deviation;
- and
- programming a sensing margin setting of the sensor device according to the sensing margin.
A method, comprising:

- and
- updating, by the device, a sensing margin setting of the sensor device according to the sensing margin.
