Smart irrigation systems have become increasingly popular in urban areas, where the need to conserve water resources is critical. These systems are designed to optimize water usage for landscaping and gardening, while also promoting sustainable and efficient irrigation practices.

2. Introduction
• Water has entered a new era where it is no longer
economically, socially, or even legally sustainable for
sites to wastewater. With UN projections showing a
40% gap in freshwater availability by 2030, it’s
paramount that companies make the effort to
effectively monitor onsite water use. For lawn and
landscape professionals, this can be accomplished by
using sensor-based irrigation controller technology.
• Smart irrigation controllers automatically tailor watering
schedules and run times based on landscape needs,
leading to more efficient outdoor water use. Unlike
traditional controllers that operate on timers, sensor-
based irrigation controllers monitor weather, soil
conditions, evaporation and plant water use to
automatically calculate new watering schedules every
day. As a result, smart irrigation controllers have been
found to conserve significant amounts of water. Several
controlled research studies indicate substantial water
savings from 40% to 70%.

4. Objectives
The goal of this project is
to design and build a
system that can
automatically control the
watering of plants and
lawns in urban areas,
using advanced sensing
and control technologies to
optimize water usage and
reduce waste.

Technology:
New Controllers
• There is a broad spectrum of smart
irrigation technology that consumers
can benefit from utilizing. Choosing
the correct technology for the situation
is essential to achieve potential water
savings. Irrigation controllers can be
separated into two main categories:
• Climate based controllers and soil
moisture-based controllers.

6. Types of Smart Irrigation
There are two different types of smart irrigation controllers:
Climate-Based Controllers (evapotranspiration)
Weather-based controllers use local weather data to adjust irrigation schedules, measuring for conditions like
temperature, wind, solar radiation, and humidity. These climate-based controllers gather local weather information
and make irrigation run-time adjustments, so the landscape only receives the appropriate amount of water.
Soil Moisture Sensor Controllers
Soil moisture sensor-based controllers use sensors that are buried in the root zone of turf, trees, or shrubs to
accurately measure the moisture level in the soil and transmit data to the sensor, which adjusts the schedule as
needed. Using both a smart irrigation controller and IoT sensor technology, these systems can be highly effective in
reducing water use, especially in hard-to-reach sites where reliable water access is difficult. The soil moisture
sensor estimates the soil volumetric water content. Volumetric water content represents the portion of the total
volume of soil occupied by water.

8. Steps Involved in Smart Irrigation
Sensor network: Develop a network of sensors that can measure key environmental
variables, such as temperature, humidity, and soil moisture. These sensors should be
distributed throughout the urban landscape to capture a range of conditions.
Control system: Design a control system that can use the data from the sensor network
to automatically control the watering of plants and lawns. The control system should be
able to adjust watering levels based on the specific needs of each plant species, as well
as changing weather conditions.
Communication system: Develop a communication system that can send alerts and
updates to maintenance staff, as well as enabling remote control and monitoring of the
system.
Energy management: Design the system to minimize energy usage and reduce the
environmental impact of the system. This could include the use of renewable energy
sources, such as solar power, to power the system.
Testing and validation: Test and validate the system in real-world conditions, collecting
data on water usage and plant health to evaluate the effectiveness of the system.

Irrigation
System
Advantages
Save manpower. Compared with traditional irrigation methods, smart irrigation is an
automated method. No need for the irrigator to walk around the irrigation field with the
nozzle. There is also no need to manually open or close the water valve. A mobile phone or
a computer can complete the entire irrigation work. No longer worry about the plants in the
garden will wilt due to lack of water when traveling. You can play anywhere with confidence.
Save water. The purpose of smart irrigation is to save water, it replaces the previous flood
irrigation. It uses less water to meet the growth needs of plants. Smart irrigation systems
can collect soil moisture data and effectively control irrigation water. It is also equipped with
a circulation system to save water resources.
Remote management. Use a mobile phone or computer to complete monitoring data
analysis and irrigation work, you do not have to appear in the irrigation area. Just turn on
the phone at the right time to observe the growth status of the plant. One person can
manage multiple cloud platforms at the same time and irrigate thousands of acres of
farmland, which greatly saves labor costs.
Fine irrigation. Based on the real-time data measured by the sensors, we adjust the
irrigation method in time. Water regularly and quantitatively according to the growth of the
plants. Irrigation evenly throughout the garden allows each flower to grow healthily.
Intelligent control. Timed irrigation, remote irrigation, and cycle irrigation, flexible switching
between the three irrigation modes, and the cloud platform modification take effect
immediately.
