Introduction: Smart Plant Watering System With Arduino

Description:

This project uses Arduino to monitor soil moisture levels and automatically activate a water pump when the soil gets too dry. It is ideal for people who forget to water their plants or are often away from home.

Attachments

Supplies

Materials Needed:

  1. Arduino Uno or Nano
  2. Soil Moisture Sensor
  3. Relay Module
  4. Water Pump (5V or 12V)
  5. Power Supply
  6. LED + Resistor
  7. Breadboard + Jumpers

Step 1: How to Build It

  1. Insert the soil moisture sensor into the plant pot.
  2. Upload the code to the Arduino.
  3. Open the serial monitor to see the sensor readings.
  4. When the soil is dry, the pump activates and waters the plant.
  5. When the soil is moist, the system stops the pump.
