Arid Architect: Smart Garden

Autonomous monitoring and watering system for a String of Nickels (succulent) using Arduino Uno and Python.

Setup Instructions

1. Hardware Connections (as per Phase 1)

Follow the wiring_guide.html for pin mappings:

• DHT11: Digital Pin 2
• Relay (Pump): Digital Pin 3
• HC-SR04: Digital Pins 4 (Trig) & 5 (Echo)
• Soil Moisture: Analog Pin A0
• Light Sensor: Analog Pin A1

2. Software Configuration

1. Python Virtual Environment:

   python3 -m venv .venv
   source .venv/bin/activate
   pip install pyserial pillow flask

2. Arduino Firmware: Upload dht11_test/dht11_test.ino to the Arduino Uno using the Arduino IDE or arduino-cli.

3. Running the System

• Manual Pulse: python3 gardener_pulse.py (reads sensors, logs data, updates dashboard).
• Automated Pulse (Cron):

  0 8,20 * * * cd /path/to/project && ./.venv/bin/python3 gardener_pulse.py

• View Dashboard: Open dashboard.html in any browser.

Project Structure

• gardener_pulse.py: The core "Heartbeat" script.
• dashboard_gen.py: Generates the static dashboard.html.
• data/garden.db: SQLite database for long-term tracking.
• photos/: Directory for daily growth photos.
• gardener.md: The "Arid Architect's" behavioral logic and thresholds.
