Roughly speaking, it measures the reaction of the plant to the humidity in the growing environment, and it is an important factor that allows to control diseases and can be manipulated.

Abstract
This chapter presents the methodology to model the temperature inside a zenith greenhouse, without crop, using a Wireless Sensor Network (WSN) and the Recursive Least Square (RLS) Technique to estimate the modeling parameters. The greenhouse size is 6mx18m, the actuators are the motors located at the windows. The WSN collects the measurements and communicates the centralized control and the actuators located in different parts of the greenhouse, it is implemented using National Instruments devices, the graphical interface is developed in LabVIEW system design. There exist a lot of work about greenhouses in the literature; however, most of them did not use mathematical techniques to model the temperature or other environment parameter. Surprisingly, just few works use RLS techniques to estimate the parameters. The main contribution of this project is to integrate the National Instruments technology and the RLS techniques in a real experimental application.
