Water is a vital element for any lawn and garden. Its utility, on the other hand, may have a considerable impact not just on the environment but also on your wallet. The United States Environmental Protection Agency (EPA) has reported that 50% of water used for outdoor irrigation is wasted. 

Remember that plants are not benefited from excess water, so it will just be a burden to the environment and will be a waste of money. For those who are concerned with water conservation and at the same time wish to save the wallet, the use of a smart irrigation controller is the best solution.

What is a smart irrigation controller?                                          

Smart irrigation controllers are a proven and advanced technology to use water effectively for outdoor irrigation purposes. 

These equipment automatically manipulate the watering schedules and the runtime to meet the moisture requirements of your garden, allowing you to use water only up to a reasonable extent while keeping your turf and the garden happy and healthy.

Unlike traditional irrigation systems, these devices are able to adjust the watering plan based on the real-time weather conditions as well as soil conditions of your landscape.

Smart irrigation controllers gather data on how much water is applied to the garden under particular weather or soil conditions. So, it can adjust the water level once such conditions are matched again.

These controllers can perform themselves using their own historic data, or you can control them with your phone, tablet, or computer. 

Most crucially, such irrigation controller devices can be controlled remotely from anywhere in the world. This will make watering your garden easier, especially when you are from a long distance from your home.

How do smart irrigation systems work?

The working principle behind any smart irrigation controller is that they monitor a condition that is related to the moisture level in your landscape in order to determine how much water to be applied and when to apply. 

In fact, these conditions can be temperature, wind, humidity, solar radiation, soil moisture level, evaporation, or plant water.

Weather-based and soil moisture-based irrigation controllers are the two main categories of smart irrigation controllers. You can choose the best type for your landscape.

When it comes to weather-based smart controllers, they are also known as evapotranspiration controllers or ET controllers, and they use local climate changes in terms of temperature, humidity, wind, and solar radiation to schedule the irrigation process.

Evaporation and transpiration are combined in the process of evapotranspiration. Transpiration is the removal of water from plant surfaces, whereas evaporation is the loss of water from the soil surface to the atmosphere.

Weather-based controllers use data related to evapotranspiration to calculate the water needs of the plants.

Weather-based irrigation controllers are available in three different forms : signal-based controllers, historic ET controllers, and on-site weather measurement controllers.

On-site weather-based smart irrigation controllers come with a sensor which monitors the temperature, humidity, or the solar radiation of the particular landscape and accordingly adjusts the irrigation schedule.

Signal-based controllers rely on the weather information that is sent to the controller from a remote weather station or publicly available weather information. Historic ET controllers use their programmed information on historic water utilities in different regions.

On the other hand, soil moisture-based controllers use information on the soil moisture level gathered by a buried probe in the root zone of the yard to schedule the irrigation.

A sensor in the buried probe determines the dampness of the soil and sends messages to calculate the precise water requirement of the yard.

Soil moisture-based controllers are two different types: water-on-demand irrigation controllers and suspended cycle irrigation systems.

Are smart irrigation controllers worth it?

Yes, these devices are worth its money. You can install a smart irrigation controller for a fairly affordable price. If you feel the initial cost for these devices is high, do not worry they won’t take much time to pay back its money for you.

In general, these controllers save 20 to 50 percent of your irrigation water consumption and thereby significantly lower your water bills within a few months.

As mentioned earlier, it has revealed that 50% of water is wasted in outdoor irrigation. Most gardeners do not have an idea about the timely water requirement of their plants when watering.

It is obvious that the water requirement of the plants varies with the environmental conditions. During wet weather, the ambient environment is well moist so the plants and the soil lose less water via evaporation.

On the other hand, during hot weather and windy climates, high temperature and the arid air contributes to withdrawing more water from the plants as well as from the soil making the plants thirstier. Hence, in such situations the plants require relatively much water.

We have often seen that most gardeners have stuck to a same watering schedule besides the environmental conditions being taken into account. This is the foremost reason for the wasting of irrigation water. So, in such a scenario higher water bills will not be a surprise.

In addition to cutting down the money for excess water, these controllers help promote the health of your garden, probably reducing the money spent on health issues of your plants.

Root rot, which is one of the most prevalent problems resulting from overwatering, can cause a huge damage to your plants.

Since smart irrigation controllers compensate the water requirements of the plants just as they need, you can get rid of such kinds of health issues.

How much water does a smart irrigation controller save?

A number of studies have been conducted to determine how effective smart irrigation controls are at conserving water. These studies have proven these devices can save 20 to 50 percent of water when compared with the traditional irrigation methods.

Smart irrigation controllers save 20% more water than traditional irrigation controllers, according to the findings of the Irrigation Association (IA) and the International Center for Water Technology at California State University.

Smart irrigation controllers can calculate the actual water requirements of the plants based on the data gathered from its surroundings.

For example, when it rains or if the soil is well moist, the controller will automatically reduce the water flow or turn off, to save water.

Therefore, these smart devices ensure optimal utilization of water while contributing to water conservation. Therefore, with the scarcity of water resources we need these types of equipment more than any other era.
