Programmable Logic Controller and μC 8051 based Automatic Irrigation System with Wireless Control

Abstract: Nowadays with increased population in world, necessities of increased productivity of land, with the use of minimum water and electricity and use of recent technologies, has been increasing day by day. This paper aims at study and demonstration of how soil humidity based irrigation of land helps to fulfill above necessities. Implementation of humidity sensor, adjustable speed drives and information and communication technology (ICT) provides many advantages from various points of view. In Vidharbha region of Maharashtra, percentage irrigation is less and whatever is present are all of traditional type; in which excessive use of water and electricity are the main drawbacks. The use of PLC and μC along with various sensors can prove a milestone in increasing the productivity of land, reducing water use thus reducing soil infertility, reducing use of electricity and making the irrigation system smart and user friendly, with considerable reduction in labor work and time of farmers. This paper discusses various features and technologies of automation in farming that can be integrated with ICT devices. This paper explains the importance of use of ASD for motor and wireless control of system, which proves important step towards smart India- smart Indians.
