Watering System - IoT Project

An automated plant watering system that reads soil moisture levels and activates a water pump to provide optimal hydration for plants. It can be built using platforms like Raspberry Pi or Arduino and communicates with a mobile application or self-hosted dashboard.

Key Features

• Soil Moisture Monitoring.
• Pump Control.
• Configurable Thresholds.
• Logging.
• Monitoring dashboard.
• Mobile notification.

Watering System Code

Raspberry Pi with Sunfounder PCF8591 Module

The watering system logic, including the moisture sensor readings, threshold comparison, and pump control, is implemented in the following file:

python sunfounder_component/watering_system.py

Raspberry Pi 5 with Adafruit ADS1115 Module and Bluetooth

To run the moisture reader using the Adafruit component, prepared with mobile integration using Bluetooth channel:

python adafruit_component/MoistureTimer.py

Arduino UNO R4 Wifi

The Arduino Uno is an affordable option for managing multiple plants. Each plant can have a dedicated Arduino that communicates with a central Raspberry Pi. For more details check the setup code in arduino/ directory.

Dashboard

Run the dashboard

cd dashboard
python3 -m http.server 8000

Dart & Flutter Application

If you would like to connect and view your moisture information through bluetooth to a cell phone, we also created a basic dart application for showing that data.

To set it up:

• install and enable dart and flutter on your PC (this typically does require setting up Visual Studio Code, Visual Studio (Community version), and Android Studio)

• build the flutter application in the "DartApp" folder

• deploy the MoistureTimedBluetooth.py file to your Pi, adjust the "interval" to your preferred update time for the moisture sensor
