This document describes an Arduino-based automatic irrigation system. The system uses soil moisture and temperature sensors to monitor soil conditions. When the soil moisture drops below a threshold, a relay connected to an Arduino board activates a water pump to irrigate. The system aims to minimize manual intervention by farmers and prevent over- or under-watering. It provides a schematic diagram of the circuit components, which include an Arduino Uno, sensors, LCD display, and relay module. The document also includes photos of the prototype and discusses the benefits of automating irrigation.

4. Introduction
• Irrigation is the artificial application of the land or soil.
• Knowing when and how much to water is two important
aspects of watering process.
• To make farming works easily, The Automatic Irrigation is
created.
• To impress the farmers for using renewable energy.

5. Objective
• To minimize manual intervention by the farmers.
• To prevent excessive wastage of water & Electricity.
• To protect the plant from instant damage.

11. Discussion & Result
• To control Relay with Motor, Arduino used. It is programmed by Arduino
IDE.
• To measure the temperature, The Temperature Sensor measures and
send signal in Arduino.
• To measure the level of soil, The Moisture Sensor senses and send signal
in Arduino.
• Finally The Pump supply the water to the water, until the desired
moisture level is reached.

12. Practical Implementation

13. Merits
• Highly sensitive.
• Works according to the soil condition.
• Low cost and reliable circuit.
• Complete elimination of manpower.
• System can be switched into manual mode whenever required.
• Irrigation in small places too like parks, garden.
• Very useful for common people who do not have time to water their
plant because of busy life schedule.
• This project is very economical in term of cost and power.

14. Conclusion
• In present days especially farmers are facing major problems in watering
their agriculture fields. Because they have no proper idea about when
the power is available so that they the can pump water. Even after then
they need to wait until the field is properly watered, which makes them
to stop other activities.
• Here is an idea which helps not only farmers even for watering garden
also, which senses soil moisture and switches the valve automatically
when the power is on
