Design of An Automated Greenhouse Temperature Controller; A Renewable, Robust and Cost Effective Scheme

Smart and automated greenhouse system is the solution of current food and agronomy related threats with growing demands and population upraise. Keeping optimal ambient condition for each crop cultivation yields to maximum production and profit figures. This research is intended to maintain ideal greenhouse temperature for a particular crop to grow. Cost effective bare tube water heating system is opted to compensate for all the dynamic and complex losses in in greenhouse for a complete day cycle. A proportional controller is designed in order to consistently monitor inside greenhouse temperature and actuate the water mass flow rate as per requirements. Designed proportional controller is able to meet the desired inside greenhouse temperature in fluctuating losses robustly.
