Questions # 21:

Scenario 1 “Happy Tomatoes” (used for questions 20-22):

An intelligent application for agricultural use incorporates temperature sensors located at different points of an enclosure. The sensors measure and record the temperature at regular intervals and extract the statistical values for these measurements. These values include the average daily temperature.

A new variety of tomatoes is currently being grown and the“World Organization for Happy Tomatoes”has established temperature ranges related to vegetative development.

When the system establishes that the average temperature is within a specific range, it emits a value that will be used to monitor and control the crop.
