This project shows the design, implementation and evaluation of an IoT (Internet of Things) based environmental monitoring system. The main idea of the work is to be able to monitor different physical properties through a web page. The system uses an Arduino UNO board to collect data from multiple environmental sensors, including DHT11 and Soil moisture sensor, to measure temperature, humidity and moisture level. The collected data is processed and sent to the ESP8266 wi-fi module, which transmits it to a web platform for visualization and the collected data will be display on LCD. To do this, an IoT network architecture has been implemented, where the Arduino collects data from the sensors and the ESP8266 is responsible for communication with the server. The communication between the devices is carried out through serial communication. A web interface has been developed using MYSQL to display the data collected in real time and at a historical level. This work demonstrates the feasibility and usefulness of an IoT-based environmental monitoring system, offering an effective and accessible solution for all users to monitor data.
