Environmental monitoring system used for autonomous irrigation station

This paper presents a smart system appropriate for environmental monitoring based on Wireless Sensor Network (WSN) using IoT systems. The meteorological sensor node used is equipped with NodeMCU ESP8266 boards and sensors to measure temperature, air humidity, and soil moisture. The locations of the nodes are sent and stored with the measured data in a MySQL database created within the Raspberry Pi 3B micro-computer used as a LAMP server. In addition, a custom graphical User Interface (GUI) is developed and associated with the WSN to facilitate visualization and interpretation of collected data through the end user. The tests were performed for a period of three weeks. Using the experimental results, automatic irrigation is provided, thereby saving time, money, and the human effort to make the agriculture smarter.
