Automatic Plant Watering System Using Microcontroller

System Overview

Components

The system includes the following components:

1. Microcontroller: The central control unit.
   • Arduino: A popular microcontroller platform used for processing sensor data and controlling the system.
2. Soil Moisture Sensor: Measures the moisture content of the soil.
   • Analog Soil Moisture Sensor: Provides an analog voltage that corresponds to soil moisture levels.
3. DC Motor: Controls the watering mechanism.
   • Submersible Water Pump: Driven by a DC motor to pump water from a reservoir to the plant.
4. Relay Module: Switches the DC motor on and off.
   • Relay: Acts as a switch to control the power to the DC motor.
5. Power Supply: Powers the microcontroller and the DC motor.
   • Adapter/Battery: Provides the necessary voltage and current.
6. Connecting Wires and Tubing: For wiring the components and delivering water to the plants.
