Overview

The project is an IoT-based smart monitoring and irrigation device for potted plants. It continuously measures:

• Soil moisture → detects when watering is needed
• Ambient temperature & humidity → ensures optimal growth

The system can automatically water the plant using a servo-controlled irrigation mechanism when the soil becomes too dry, while also allowing remote monitoring via Wi-Fi and cloud integration.

Technologies

• ESP32 DevKit v1 (Wi-Fi microcontroller)
• Sparkfun Capacitive Soil Moisture Sensor
• BME280 for temperature and humidity
• ADPS9960 proximity sensor
• 2.4-inch TFT LCD display
• Servo motor with irrigation mechanism
• 9V power supply + buck converter
• Software: PlatformIO, MQTT

Design & Fabrication

• Custom 3D-printed case designed in Fusion 360
• Custom PCB designed in KiCad

Future Plans

• Expand system for larger gardens with multiple zones.
• Centralized dashboard for all irrigation zones.
• Integrate weather forecasts for smarter watering.
• Explore solar-powered sustainable setups.
