Automation Of Greenhouse

Abstract

Automating a greenhouse envisages monitoring and controlling of the climatic pa- rameters which directly or indirectly govern the plant growth and hence their pro- duction. It automatically controls the environment parameters using sensors for feedback and actuators for control. This real-time automation for large Green- houses would enable controlling environment automatically based on the configured settings for different plants/crops and continuous measurement of temperature, hu- midity, and soil moisture of the Greenhouse. In the solution for this automation, user sends required parameter values according to crop requirements from look up tables to the master board from a mobile application through SMS over GSM com- munication. Micro-controller on master board will receive these parameter values from its GSM module through UART and send it to ZigBee module on the master board. These data are further sent from master board ZigBee to slave board ZigBee over ZigBee communication. The microcontroller on slave board will receive this data from its ZigBee through UART and sent these parameter values to relays connected to actuators to turn these relays on and of accordingly.The sensors at slave boards continuously give measured parameters values to the microcontroller through ZigBee. Microcontroller compares sensors feedback with users applying parameter values and according to that error microcontroller switches on and of actuators. This setup on greenhouse automation will control the actuators (fan, fogger, drip irrigation) based on feedback from sensors and parameter values set by greenhouse owners. Communication from owner to greenhouse will happen through GSM module and within greenhouse will happen through ZigBee. We performed the same with Arduino uno and received better results for the automation. Further, the integration of IoT in this automation makes it much easier to per- form with a greater extent of monitoring and control. ThingSpeak is the cloud used in this project to store the greenhouse data and act upon it using various actions. We send sensor data to a channel created by us on ThingSpeak which is shown as various plots. Then we can analyze the data and take action on it using various facilities provided by this cloud like MATLAB analysis, pulgins, TweetControl. EAGLE for PCB designing is a great tool for students, hobbyists and others as it provides all convenient resources for designing.
