Rain sensors and irrigation

Rainwater is irrigated for free, but not all rainwater is available. If you don’t measure and use rainwater irrigation properly, you could be wasting your garden’s valuable free asset. It doesn’t matter if you’re managing 1,000 acres of land, a small home garden, or a nice view. Understanding these four concepts will help you become a better water manager. To understand the rainfall situation, you can use the JXCT rainfall sensor, which can help you better understand the situation, better understand the plant needs.

How much rain can a heavy rain fall?

Rainfall in your garden is often described as light, moderate or heavy, but how many waterfalls do these descriptions include? Light rain is considered less than 0.1 inches of rain per hour. Moderate rainfall is defined as 0.10 to 0.30 inches per hour. The rain was more than 0.30 inches per hour. These descriptions provide two factors, rainfall over a period of time (one hour). This is basic information to know, but it’s not enough on its own to decide how much water to water.

Understand the concept of effective precipitation

EP is the amount of rainwater that is added and stored in the soil. If your soil is dry and you experience light rain, most of it will evaporate from the surface of the soil and will not be used by your plants. Conversely, if your soil is clay and experiences a heavy one-inch rain in a few hours, your soil will not be able to absorb the rain and most of it will run off and be wasted. A rain sensor can help you understand the amount of rainfall, but soil moisture requires a soil sensor

Understand the penetration rate of soil

Knowing your soil type (here’s a link on how to do a soil test) is the first key to knowing your permeability. Permeability is helpful because it helps determine how much rainwater is available. If rainfall exceeds the soil’s permeability, the soil is wasted. Rain that falls below the soil’s capacity evaporates and cannot be used by plants.

How wet is your soil when it rains

The final factor to get the most out of rainfall is how moist the soil is when it rains. If you water the day before it rains, most of it will be wasted. If you water normally the day after moderate or heavy rain, most of the irrigation will be wasted as well.

Use a smart controller to schedule irrigation in your garden using rainfall
Using an intelligent controller like the JXCT controller makes all of these calculations easy because the controller can do all of these calculations for you. JXCT measures rainfall, calculates effective precipitation based on your soil type, knows your current soil water balance, predicts rainfall events, and automatically adjusts irrigation plans. These calculations are done on an hourly basis so that you get the most out of the rain.
