#MAP011 Roof Garden Automation Using Android Mobile Control.

Roof Garden Automation Using Android Mobile Control.

Description:

This system automates the irrigation of a roof garden using a soil moisture sensor and a water pump, all controlled remotely via an Android mobile app. The app communicates with the system (via Bluetooth or Wi-Fi) to manually or automatically water the plants based on real-time soil conditions. It enhances urban gardening by reducing manual effort and optimizing water usage.

Materials:

• Arduino board (Uno/Nano)

• Soil moisture sensor

• DC water pump

• Relay module (to control the pump)

• Bluetooth module (HC-05) or Wi-Fi module (ESP8266)

• Android smartphone

• Power supply (battery or adapter)

• Jumper wires

• Water tubing

• Water reservoir/tank

• Breadboard (optional)

Working Principle:

1. The soil moisture sensor measures the moisture level in the soil.

2. The data is sent to the Arduino, which compares it with a preset threshold.

3. If moisture is below the threshold, the Arduino activates the water pump via the relay.

4. The Android app allows manual pump control or displays real-time status via Bluetooth/Wi-Fi.

5. When soil reaches adequate moisture, the pump turns off automatically.

Advantages:

• 📱 Remote Control – Water your garden anytime from your phone
