Modbus Based Multinode Irrigation Automation
As the people know that cultivating some plants and flowers in a closed environment requires precise control of humidity, temperature, light intensity and becomes risky and difficult. So if the people automate this process by using sensors and actuators whose settings are set accordingly by the user then the work and burden of the farmer gets reduced to maximum extent. In this paper, the authors are designing this system, where they place a slave device in the land slots which acquire the data and send it to one main master device. The slave and master communicates through RS485 network using mod-bus protocol which is cheap and yet effective. So that the user can monitor and control each and every node from the master itself.
