| Popis: | The main aim of this study is to develop a smart system to monitor and control the soil condition of the street trees in a smart city. In this proposed system, a wireless sensor network was developed to collect the soil condition of the trees, an automatic irrigation system was constructed for watering street trees and a graphical user interface was developed to evaluate the performance of the system. NodeMCU ESP8277 is being interfaced with a moisture sensor for the volumetric water content in soil, humidity and temperature sensor for the surrounding environment, rain sensor for detecting rain and relay to control the valves. MQTT broker is used to acquire the data and control to and from NodeMCU ESP8266 and to be interfaced wirelessly with the Node-Red. Thus, the system is controlled and monitored wirelessly with the help of the developed integrated Graphical User Interface. A secured wireless communication system for data transmission was achieved by using NodeMCU ESP8266 and raspberry pi microcontroller. The graphical user interface was built in Node-Red which is IoT platform to evaluate the performance of the system, it displays the data in an interactive method and it can be used for controlling the irrigation system remotely. The data were transmitted with no delay or losses of data and the system was controlled automatically and remotely. |
