Abstract
The present embedded system has been design and developed in order to measure, display and control polyhouse related environmental factors such as humidity, soil moisture and temperature by using 89E516RD microcontroller. In order to maintain favorable condition for plant growth in polyhouse the humidity sensor, soil moisture sensor and temperature sensor along with microcontroller are deployed. The micro-controller based embedded system sense and display information on 16x2 LCD display and also provides automated ON-OFF control action for exhaust fan, heater and fogger. The result in the graphical format shows the response of embedded system under discussion. This system is cost effective, easy handling and has compact hardware.
Highlights
The traditional open field plant growing techniques are facing great challenges due to excessive climatic conditions especially in very less and heavy rainfall areas [1]
The agricultural growth is getting disturbed in timely exports, which results in less crop production and heavy import of agriculture goods
There is a need to look for alternative technologies to increase agricultural yield
Summary
The traditional open field plant growing techniques are facing great challenges due to excessive climatic conditions especially in very less and heavy rainfall areas [1]. The use of efficient inputs must be improved and the latest technological developments must be practiced to fulfill the needs of national as well as export oriented nutritional target foods [2]. The latest practice has shown huge improvement in polyhouse technology in diversified fields such as plant science, soil science, weed science, plant pathology, and water technology and water agronomics. Polyethylene shed net helps to construct a polyhouse which provides artificially controlled environment for plant growth [3]. The controlled environment can be accurately measured and controlled in a polyhouse for improvement in crop productivity, quality and IJAAST – An Open Access Journal (ISSN 2320 – 026X)
