What You Should Know Before Installing a Soil Moisture Sensor

Soil moisture sensors are devices that measure the volumetric water content of soil. By using these devices, you can improve your irrigation efficiency. However, there are some things you should know before installing a soil moisture sensor. These include the requirements for installation and the different types of soil moisture sensors. The following article will give you some information to help you decide which sensor is best for your needs.

Measuring volumetric water content in soil

Measuring volumetric water content in the soil is an essential part of agriculture, forestry, and environmental science. It is also critical to the search for life on Mars. In addition to researchers, farmers, horticulturists, turf managers, and government agencies need accurate measurements of water content. In recent decades, researchers have been developing new methods for measuring soil moisture.

To measure volumetric water content in soil, you first have to determine the total mass of the soil sample. The mass of the soil sample, including water, is expressed in grams (g). You can calculate the volumetric water content by calculating the mass per unit mass. Then divide the mass by the total mass to obtain the total weight of the soil sample.

Using a soil moisture sensor to improve irrigation efficiency

Soil moisture sensors can improve the efficiency of irrigation while saving water and boosting yields. However, their adoption has been slow. According to a recent study from the U.S. Department of Agriculture, only 10 percent of irrigated farms were using this technology. That figure has now increased to 12%, with California, Mississippi, and Nebraska leading the pack.

When using soil moisture sensors, it is important to ensure they are installed properly. This means avoiding sensors that are too large for the area they will be installed in. Also, sensors must be installed away from slopes and high points. Additionally, sensors must be installed in soil with different textures, so it is important to make sure the soil sample is representative of the type of soil to be monitored. Additionally, sensors that are installed with a data logger can help you interpret the data and make informed decisions based on that information.

Requirements for installing a soil moisture sensor

There are a few things you should know before you install a soil moisture sensor. First, make sure the soil moisture sensor is free of air bubbles, as these can cause inaccurate readings. It is also very important to keep the wire leads above ground. Also, remember to calibrate the sensor, as it may need to be adjusted for different environments.

Next, you need to know the type of sensor you are going to install. You can choose the soil matric potential sensor, which has a 48-inch probe. In order to install this type of sensor, you need to make a pilot hole in the soil. Make sure there are no lumps in the soil, as this will damage the sensor. Then, use a shovel to make a hole in the soil around the sensor.

Common types of soil moisture sensors

There are several types of soil moisture sensors available on the market. These devices measure soil moisture and can help you schedule irrigation. In addition, they can measure soil tension and volumetric water content. To find out which one is right for your needs, consult a soil moisture 201: methods and applications article.

Gypsum block soil moisture sensors have two electrodes embedded in a block that is porous, allowing them to absorb water. When water enters the block, the electrodes generate an electrical resistance, which is then measured with a handheld meter. The resistance reading is then converted to a percentage value that tells you how much water is in the soil. These sensors are simple to install and are inexpensive.

Soil moisture sensors can be buried in the soil indefinitely or connected to a handheld reader or data logger. There are battery-operated versions that are small enough to be used anywhere, and a wireless remote telemetry option allows for data to be transmitted to a cloud-based platform. The data is stored on the logger and uploaded hourly to a subscription service for further analysis.

Cost of soil moisture sensors

Soil moisture sensors are a valuable tool to help you monitor soil moisture. They help you avoid over-watering, which leads to runoff and can damage plants. By detecting the moisture level, the sensors can prevent irrigation from happening until it is needed, saving thousands of gallons of water every year. In addition to using soil moisture sensors, there are several other ways to help reduce irrigation water consumption. Some tips include aerating soil to increase root accessibility and adding compost. These practices will help you save forty to sixty percent of water. You can also use mulch to lock in moisture and reduce evaporation.

Soil moisture sensors can also be used to monitor the soil moisture of houseplants and shrubs. They use a sensor with a variable voltage output and can turn on/off when the soil moisture level exceeds a certain value. There is a potentiometer on the sensor's spade, which can be used to set the sensor's threshold. They also have a LM393 chipset, which helps them measure the moisture content of soil.

Smart Irrigation Controllers

There are a variety of smart irrigation controllers that can help you manage your lawn and garden watering more effectively. Some are designed to work based on weather and soil moisture information, and some are based on the plant's needs. Both types of smart irrigation controllers can be used strategically in a landscape. The choice of controller will depend on plant type, soil moisture, and location.


One of the best ways to save water when irrigation isn't working is by using smart irrigation. This type of system uses water-on-demand technology to automate the irrigation process and save water by eliminating the need to manually program the duration of irrigation. The system works by monitoring the soil moisture and initiating irrigation when it reaches a certain level. In controlled research studies, the system saved substantial amounts of water.

The technology enables smart irrigation by determining when to water plants based on environmental conditions, such as soil moisture, temperature, and other variables. It uses sensors to monitor moisture levels in soil and transmits the data to a controller. There are two main types of soil moisture sensor systems. The first type allows the user to set upper and lower moisture thresholds for their plants and automatically starts irrigation when these conditions are met.

Suspended cycle

Suspended cycle irrigation systems use a soil moisture sensor to automatically adjust watering cycles and avoid overwatering your garden. These sensors are buried into the root zone of your plants and send readings to a controller. The controller then takes action based on this information. The system will stop watering when the soil reaches a certain moisture level.

The system can be upgraded to a "smart" version by adding on equipment and sensors. Advanced models include WiFi modules for real-time alerts and advanced water management tools. These systems allow you to remotely monitor and adjust irrigation cycles with real-time weather information and other data. If you'd like to use smart irrigation for your garden, the SMRT-Y soil moisture sensor kit can help you achieve that.

Another important aspect of IoT irrigation is its communication system. It must be effective and able to communicate with other devices. In IoT for irrigation, there are two main types of communication systems: the lower layer consists of actuators and the middle layer is made up of gateways and clouds for data exchange. These two technologies can work together or independently, enabling you to get better results and minimizing errors.


If you're trying to save water and maintain plant health, a weather-based smart irrigation system can be the best choice. It stores weather data from your field in a remote database, allowing it to automatically adjust water supply based on the current weather conditions. These smart irrigation systems can save up to 40 percent of water and increase plant health exponentially.

Weather-based smart irrigation systems use weather data and sensors to determine the best times to water your plants. They also take into account losses of water through evaporation and transpiration from plants. This is all based on a wide range of variables, including local temperature, humidity, and insolation state.

A weather-based smart irrigation system can save up to 7,600 gallons of water per year. If every household in the United States installed such a system, the water savings could be $2.5 billion and 220 billion gallons each year. Some utilities offer rebates to users who install and use weather-based irrigation controllers.
