Polyhouse Automation Using PLC

Abstract: Poly-house is basically naturally ventilated climate controlled system. In poly-house various crops are grown under their favourable environmental conditions. Environmental conditions such as temperature within the poly-house, humidity of soil and atmosphere etc. Every crop needs different climatic conditions and to provide that conditions farmers need man power to do labour work. The system we designed and implemented on small working model of poly-house reduces labour and man power. The info about favourable condition and need of plant is provided by the various agricultural universities and agricultural experts. Today we have cheap sensors and more precise and programmable controllers such as PLC available in the market. With the help of temperature, light intensity, humidity sensors and PLC automation of poly-house can be done. With the help of automation minimum and effective use of valuable resources can lead to achieve maximum crop.
