Soil Moisture and Humidity Display with Circular Bar

Project Overview:This project involves monitoring soil moisture and humidity levels using an Arduino Nano board, a DHT11 sensor, and a GC9A01A TFT display. The data can be visualized in real-time through a web application, though the final version was made using an Arduino Nano due to the previous ESP8266 board being burned by high voltage.

Reason for Creation:I wanted to create a reliable and accessible system to monitor environmental conditions for plant care. The project also includes cloud-based monitoring through Firebase for remote access, but the original plan was altered due to hardware issues with the ESP8266. Also made a compact circuit for this project.Find the Project files including web application, circuit diagram and the code here - https://github.com/Gavinduachintha/plant_monitoring_system

How It Works:

• Soil moisture is measured with an analog sensor connected to the Arduino Nano, while humidity is measured using the DHT11 sensor.
• The data is processed and displayed on the TFT screen.
• The system originally used an ESP8266 for cloud communication with Firebase, but due to the ESP board being damaged, the final version now uses the Arduino Nano for local monitoring.
