A Design of a Remote Greenhouse Monitoring and Controlling System Based on Internet of Things

摘要

The greenhouse has become one of the most important areas of internet of things application, due to its capability to replace the cables used to transfer the measured greenhouse parameters with damage avoidance. This paper aims to implement this capability by designing a remote greenhouse monitoring and controlling system. The proposed system collects the greenhouse parameters such as temperature, relative humidity, and light intensity and transfers it to a raspberry pi act as a server in real time based on internet of thing technology. This system composed of sensor nodes unit, collecting and controlling unit, monitoring unit, and actuating unit. The methodology of this system include four steps: Firstly, the sensor nodes collect the greenhouse parameters and transfer it to the server through ESP8266 Wi-Fi module. Secondly, the server collects these measured parameters from the sensor nodes, post it on the internet through MQTT protocol, and compares it with appropriate parameters for crop growth, if any changes occur the server sends frame to the actuating unit to perform action according to that. Thirdly, the monitoring unit shows graph for currents temperature, relative humidity, and light intensity values by using Red-Node software and users can monitor their greenhouse online by visit the web site of the system. Finally, the actuating unit provides optimal condition inside the greenhouse. The experiment test of this system allows distributed monitoring, provides more accurate control of crop conditions, the data can be accessible in the internet from anywhere, and reduce the human effort. Further work, measure all the greenhouse parameters.
