Design and Implementation of Green House Data Logger for Optimum Crop Production

Abstract

Greenhouse technology is a viable option for sustainable crop production in regions of adverse climatic conditions. During hot seasons the heat input to a greenhouse causes the internal temperature to exceed its optimal value. The present study was devoted to constructing an evaporative cooling system to reduce heat stress inside a greenhouse. The use of greenhouses with controlled microclimate according to the plant's needs is an important way to increase the production of fruits and vegetables and has recently become one of the hottest topics in precision agriculture. To know and control the greenhouse microclimate, smart sensing nodes with wireless communication capabilities are recommended. This paper presents a review of the use of technologies for automated activities in greenhouses.  Different microclimate parameters inside the greenhouse are to be precisely controlled for successful greenhouse cultivation or to maximize production. Controlling can be done either by manually or by an automatic control system which comprises measurement, data processing, recording and management of environmental parameters. The manual method of control is not accurate, very time-consuming and very laborious process. Hence automatic control of microclimate is required for better performance of the greenhouse. Different methods of automation of the greenhouse include the use of microprocessor-based control systems and computer-controlled systems. Computerized control is more accurate but not economical for small and medium farmers. Microprocessor-based control is good for small farmers.
