Why Everyone Loves Using irrigation system Controllers

Background:

In the United States, outdoor water use alone averages over 9 billion gallons per day, primarily for landscape irrigation. As much as 50% of water is wasted due to overwatering due to traditional irrigation methods and system inefficiencies. Smart irrigation technology is the answer. Smart irrigation systems automatically customize watering schedules and run times to meet specific landscape needs. These irrigation controllers significantly increase outdoor water use efficiency.

Unlike traditional irrigation controllers that run on preset programs and timers, smart irrigation controllers monitor weather, soil conditions, evaporation and plant water use to automatically adjust watering schedules based on site conditions.

For example, as outdoor temperatures increase or rainfall decreases, smart irrigation controllers consider site-specific variables such as soil type, sprinkler application rates, and more to adjust watering run times or schedules. There are several options for smart irrigation controllers.

Based on the difference between weather and soil moisture sensors

There are basically two types of smart irrigation system controllers: weather-based (ET) and on-site soil moisture sensors. The right solution depends on your geographic location and landscape setting.

Weather-Based Smart irrigation system controller

Weather-based controllers, also known as evapotranspiration (ET) controllers, use local weather data to adjust irrigation schedules. Evapotranspiration is the combination of evaporation from the soil surface and transpiration of plant material. These controllers collect local weather information and adjust irrigation run times so that the landscape receives the right amount of water. Weather data uses four weather parameters: temperature, wind, solar radiation, and humidity. This is the most accurate way to calculate your landscape water needs.

These weather-based controllers come in three basic forms:

The signal-based controller uses weather data from publicly available sources and calculates ET values for the grass surface on site. The ET data is then sent to the controller via a wireless connection.
Historic controllers use pre-programmed water usage curves based on historical usage in different regions. The curve can be adjusted for temperature and solar radiation.
The Field Weather Measurement Controller uses weather data collected in the field to calculate continuous ET measurements and corresponding water volumes.
Soil Moisture Sensors for Use with Smart irrigation system Controllers
Smart irrigation controllers based on soil moisture sensors use one of several proven technologies to measure soil moisture levels. When buried in the root zone of turf, trees or shrubs, the sensor can accurately determine the moisture content in the soil and transmit that reading to the controller.

There are two different soil moisture sensor based systems available:

A pause cycle irrigation system that is set up like a traditional timer controller with a watering schedule, start time and duration. The difference is that the system stops the next scheduled irrigation when there is enough moisture in the soil.
On-Demand Watering No need to program watering durations (just start time and days of the week). It has a user-set lower and upper threshold, and it initiates irrigation when soil moisture levels fail to meet those levels.

Automatic Irrigation Controller system

The automatic irrigation controller system can realize the control of the irrigation solenoid valve and the irrigation frequency conversion control cabinet. The irrigation system controller can remotely control the solenoid valve to save water. It can control the solenoid valve through two ways of buttons and cloud platform.

The wireless irrigation controller is divided into 2 channels and 1 channel. The 2-channel irrigation controller can realize remote control of irrigation, control whether soil moisture detection is activated, automatic irrigation control, and button control; 1. The channel irrigation controller can realize remote control of irrigation and control whether soil moisture detection is activated, and automatic irrigation control.
