Renke Soil Sensor Types

In order to measure different soil and different soil parameters, we have developed a variety of soil sensors. These soil sensors are cheap peice and easy to operate. Please choose your best sensor.

Soil moisture sensor description

Renke soil moisture sensor is a high-precision sensor for measuring soil moisture. The working principle is to measure the dielectric constant of the soil, which can measure the volume percentage of soil moisture. The soil moisture measurement method conforms to international standards and is suitable for various soils.

Soil moisture sensor

The soil moisture sensor(RS-SD-*-TR-1) is the most common device to measure soil moisture content. It can be connected with related instruments to become a plug-and-measure portable soil moisture meter, or it can be connected to a general data collector to realize long-term dynamic monitoring. Our soil moisture sensor adopts the TDR frequency domain reflection principle, which makes the measurement faster and more accurate.

  • Probe length: 70mm
  • Probe diameter: 3mm
  • Probe material: 304 stainless steel
  • Sealing material: epoxy resin (black flame retardant)
  • Cable length: standard two meters
  • Protection level: IP68
  • Soil moisture measurement area: within a cylinder with a radius of 7cm centered on the central probe

Soil temperature and humidity sensor

The soil temperature and humidity sensor(RS-WS-*-TR-1) can measure the two elements of soil temperature and humidity at the same time. It is a sensor for agriculture. The soil temperature is closely related to the growth and development of crops, the decomposition of fertilizers, and the accumulation of organic matter. It is an important environmental factor in agricultural production.

Renke provides an integrated soil sensor to measure soil moisture and send this data to the cloud, where it can be accessed through a free cloud platform anytime, anywhere.

3 in 1 Soil sensor

The soil temperature humidity and EC sensor(RS-ECTH-*-TR-1) is an important tool for observing and studying the occurrence, evolution, improvement, and water and salt dynamics of saline soil. The 3 in 1 soil sensor creatively measures salinity, moisture, and temperature together, which greatly facilitates the customer’s systematic assessment of soil conditions. By measuring the dielectric constant of the soil, it can directly and stably reflect the true moisture content of various soils.

Our soil moisture sensor is durable and can provide accurate data even in extreme temperatures, regardless of soil type. The protection grade of the Renke soil sensor is IP68. There are multiple options for output mode such as rs485, 0-5v, 0-10v, 4-20ma, etc.

Soil moisture sensor application

The soil moisture sensor is suitable for soil moisture monitoring, scientific experiments, water-saving irrigation, greenhouses, flowers and vegetables, grassland pastures, soil rapid testing, plant cultivation, sewage treatment, precision agriculture, and other occasions. Soil moisture sensor can be combined with wind speed sensor, wind direction sensor, rain gauge, solar radiation shield, rain and snow sensor, UV sensor, solar radiation sensor, sunlight sensor, atmospheric pressure sensor, etc. to form a weather station monitoring system.

Soil moisture sensor features

1. The three parameters of soil moisture content, electrical conductivity, and temperature are combined into one.
2. It can also be used for the conductivity of water and fertilizer integrated solutions and other nutrient solutions and substrates.
3. The electrode is made of specially treated alloy material, which can withstand strong external impact and is not easy to damage.
4. Completely sealed, resistant to acid and alkali corrosion can be buried in soil or directly into the water for long-term dynamic testing.
5. High precision, fast response, good interchangeability, probe insertion design to ensure accurate measurement and reliable performance.

How to install a soil moisture sensor?

Since the electrode directly measures the conductivity of the soluble salt ions in the soil, the soil volumetric water content must be higher than about 20% when the soluble ions in the soil can accurately reflect the conductivity of the soil. In the long-term observation, the measured value after irrigation or rainfall is closer to the true level. If performing a quick test, water the soil to be tested first, and then measure after the water is fully penetrated.


If you are measuring on a hard surface, you should drill the hole first (the hole diameter should be smaller than the probe diameter), then insert the soil and compact the soil before measuring; the sensor should be protected from severe vibration and impact, let alone knocked with hard objects. Because the sensor is a black package, the sensor will heat up rapidly (up to 50℃) under strong sunlight. To prevent the excessive temperature from affecting the temperature measurement of the sensor, please pay attention to shading and protection when using in the field or the field.

What is the output of the soil moisture sensor?

Our company provides customers with four output modes: RS485 Modbus, Lora, 4-20ma, 0-5v, and 0-10v.

Where to place the soil sensor?

  • Place the fixed sensor between the plants at the desired depth.
  • Mark the place where the sensor is placed to prevent the sensor from being damaged
  • Do not install the sensor near the pivot wheel track, and make sure that the sensor is in direct contact with the soil and has minimal interference to the soil during the installation process.
