Semi-automated Polyhouse Cultivation using LabVIEW

Prathiba Jonnala

Abstract


The optimum solution for polyhouse maintenance with minimum hardware and human effort has developed. By using this proposed model the temperature inside the polyhouse can be measured and controlled. For measuring the temperature LM35 sensor has used. And for making polyhouse at constant temperature cooling fan has taken. By using national instruments ELVIS-II board these hardware components are interfaced. The overall implementation has done with the help of LabVIEW programming. The proposed model provides the cost effectiveness and has the advantage of easy installation. This model operated on the given threshold value of temperature. Whenever the temperature increases beyond the programmed value the cooling fan will starts working to lower the temperature without any further manual instruction. By provision of this automatic cooling function the human effort can be reduced to maximum level to make the cultivation in a fruitful way by making optimum conditions for the growth of the plants. For this proposed model the threshold value temperature has taken as 35oC. The status of the environmental conditions inside polyhouse can be observed in the computer with the help of LabVIEW. The GUI provided by LabVIEW shows the value of temperature and its conditional parameters and status of cooling fan.
