Abstract

A method, a computing system and a computer program product are provided for utilizing supplemental sensors to monitor conditions of an area employing a sensor network. One or more supplemental sensors that are external to the sensor network are detected in an area. The one or more supplemental sensors are added to the sensor network. Readings pertaining to the conditions of the area are retrieved from the detected one or more supplemental sensors and one or more first sensors included in the sensor network. The readings of the one or more supplemental sensors and the one or more first sensors are compared and a resulting condition of the area is determined based on the comparing.

determining a respective type of the each supplemental sensor added to the sensor network; and

querying the each supplemental sensor for readings in accordance with the respective determined type.

3. The method of claim 1, wherein one or more of the each respective supplemental sensor added to the sensor network include a sensor of an Internet of Things device.

4. The method of claim 1, wherein the determining a resulting condition further comprises:

overriding a condition indicated by the sensor network in response to a variance in the readings between the one or more supplemental sensors assigned to one of the respective areas and the one or more fixed sensors included in the one of the respective areas.

5. The method of claim 4, wherein the determining a resulting condition further comprises:

determining a first number of sensors in the one of the respective areas reporting a first condition and a second number of sensors in the one of the respective areas reporting a second condition; and

determining the resulting condition based on which of the first number and the second number is a higher number.

6. The method of claim 5, wherein the plurality of fixed sensors are weighted differently than the each respective supplemental sensor when performing the determining of a first number of sensors and a second number of sensors.

18. The method of claim 1, wherein:

the computer system determines a closest fixed sensor to the each respective supplemental sensor based on signal strength information regarding a signal detected from the each respective supplemental sensor.

7. A computing system for monitoring conditions of a plurality of areas employing a sensor network, the computing system comprising:
