Water Usage & Arduino Irrigation Systems

Water Usage & Irrigation

• According to the AQUASTAT database in 2010, the agriculture sector consumed 69% of the world's freshwater supply, while industrial and domestic usage accounted for 19% and the remaining percentage, respectively.
• Sensor-based automated irrigation systems offer a solution to the need for farmers' physical presence in their fields for irrigation.
• These systems can remotely control water supply to plants, making them more efficient and allowing farmers to pursue other occupations.
• A smart drip irrigation system utilizes Raspberry Pi and Arduino technology for home automation, efficiently delivering water to plants through narrow tubes and valves.

Arduino-Based Automatic Plant Watering System

• The system uses Arduino microcontroller, moisture sensors, and a motor/pump.
• The microcontroller receives data from the moisture sensor and controls water delivery based on pre-programmed instructions.
• The moisture sensor measures soil moisture levels and sends the data to the microcontroller.
• If the soil is dry, the microcontroller activates the motor/pump to irrigate the plants.

System Design

• The system features a microcontroller block, a sensor block, and a hardware implementation block.
• The microcontroller is responsible for processing data and controlling the system.
• The moisture sensor measures the soil moisture level.
• The hardware implementation includes the components needed for the operation system.
• The LCD screen displays the moisture sensor readings and the status of the water pump.

Code and Functionality

• The system's code reads the sensor value and displays it on the LCD screen.
• The code converts the analog sensor value into a digital representation and determines whether to activate the water pump.
• If the soil moisture percentage is below 38%, the water pump will be automatically switched on.
• The LCD screen will display "ON" when the water pump is active.
• The code is responsible for the efficient use of water and the automation of the irrigation process.

This quiz explores the critical role of water consumption in agriculture, highlighting the statistics from the AQUASTAT database. It delves into innovative solutions like sensor-based automated irrigation and the implementation of Arduino in smart drip systems for efficient water management.
