Soil sensors

also known as soil moisture sensors or soil moisture meters, are devices used to measure and monitor the moisture content
and other important parameters of soil. They play a crucial role in agriculture, landscaping, environmental monitoring, and research applications.

Soil sensors utilize different sensing technologies to provide accurate measurements and data about the soil conditions. The most common type of soil sensor is the moisture sensor, which measures the volumetric water content (VWC) of the soil. Other soil sensors may measure parameters such as soil temperature, soil conductivity, soil pH, and nutrient levels.

Types of soil sensors

PH Soil Sensor

NPK Soil Sensor

soil moisture sensor

A soil moisture sensor is a device used to measure the moisture content per unit volume of soil. It typically represents moisture content by measuring certain other characteristics of soil, such as resistance, dielectric constant, or interaction with neutrons.

Application of soil sensors

When the soil temperature and humidity sensor is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouse, flowers and vegetables, grassland and pasture, soil rapid detection, plant cultivation, sewage treatment, precision agriculture and other occasions. When Soil moisture sensor can be combined with wind speed sensor, wind direction sensor, rain gauge, solar radiation shielding, rain and snow sensor, ultraviolet sensor, solar radiation sensor, sunlight sensor, atmospheric pressure sensor into a weather station monitoring system.


(1)High protection performance: 

When High-density epoxy resin is used for high-temperature vacuum filling between the probe and the body, which can prevent moisture from entering the inside of the body and has a better sealing performance. In addition to the combined part, we also do waterproof and dustproof treatment to the entire body to ensure long-term operation of the components.


WhenWe use austenitic 316 stainless steel as the raw material for the probe part, which is anti-rust, electrolytic, and salt-alkali corrosion resistant, ensuring the long-term operation of the probe part. Therefore, it is suitable for all kinds of soil.
(3)Internal structure: low power consumption and high sensitivity chip, the soil sensor uses imported high quality chip inside, low power consumption, high sensitivity and stable signal.

How to maintain soil sensors

Soil Sensors

Maintaining soil sensors is crucial to ensure accurate and reliable soil moisture and temperature measurements. Here are some general tips on how to maintain soil sensors:

  • Regular Cleaning: Soil sensors can accumulate dirt, debris, and salt deposits over time, which can affect their accuracy. Regularly clean the sensors using a soft brush or compressed air to remove any accumulated material.
  • Calibration: It’s important to calibrate soil sensors periodically to ensure accurate measurements. Follow the manufacturer’s guidelines for calibration procedures and frequency to maintain the sensor’s accuracy.
  • Check Connections: when Inspect the sensor connections regularly to ensure they are secure and free from c orrosion. Loose or corroded connections can lead to unreliable data.
  • Professional Servicing: Consider periodic professional servicing of the soil sensors, especially if they are part of a larger monitoring system. Professional technicians can perform detailed inspections and maintenance to ensure optimal performance.

How to clean the soil sensors

To clean the soil sensor, you can follow these steps:

  • Disconnect the sensor:When Ensure that the soil sensor is not connected to any power source or data logger before starting the cleaning process.
  • Remove excess soil: Gently remove any excess soil or debris from the sensor using a soft brush or cloth. Be careful not to damage the sensor or its components.
  • Rinse with water (optional): If the soil sensor is waterproof or water-resistant, you can rinse it with clean water to remove any remaining dirt or particles. Avoid using excessive water pressure, as it may damage the sensor.
  • Use a mild detergent (if necessary): If the sensor is still dirty or has stubborn stains, you can mix a mild detergent with water and use a soft cloth or brush to gently scrub the sensor surface.When Ensure that the detergent is compatible with the sensor material and does not leave any residue.
  • Dry the sensor: After cleaning, allow the sensor to air dry completely. Avoid using heat sources or direct sunlight, as they may affect the sensor’s functionality.
  • Reassemble and test: Once the sensor is fully dry, reassemble it according to the manufacturer’s instructions. Before reusing the sensor, perform a test to ensure that it is functioning properly.
