 NBL-S-TM Resistive Soil Temperature and Moisture Sensor Technical Specifications

 NBL-S-TM Soil Temperature and Humidity Sensor Working Principle:

- Soil Moisture Measurement: NBL-S-TM sensor adopts Frequency Domain Reflectance (FDR) technology, which calculates the dielectric constant by sending high-frequency electromagnetic waves into the soil and analyzing the time delay and amplitude change of the reflected waves, and then deduces the soil moisture content. The dielectric constant of the soil is directly proportional to the moisture content, thus accurately reflecting the true moisture status of the soil.

- Soil temperature measurement: A thermistor (NTC) is used to measure soil temperature. The resistance value of the thermistor changes with temperature, and the soil temperature can be accurately calculated by measuring the resistance value.

  NBL-S-TM Soil Temperature and Humidity Sensor Installation and Measurement Methods

 Quick Measurement Method

1. Choose a suitable measuring place, avoiding stones or hard objects.

2. Plan the top layer of soil to maintain the original looseness of the soil.

3. Insert the sensor vertically, avoid shaking, and make sure it is in close contact with the soil.

4. It is recommended to take several measurements at the same measuring point to find the average value to improve the accuracy of measurement.

 Buried measurement method

1. Dig a hole with a diameter of more than 20cm to reach the required depth. 

2. Insert the sensor probe horizontally into the hole wall at the desired depth. 

3. Fill and compact the hole to ensure that the electrode is in close contact with the soil.

4. After stabilization, measurements can be taken continuously for days, months or longer.

 Precautions for installing the soil sensor

- When measuring on hard ground, drill a hole smaller than the diameter of the probe, insert the sensor, compact the soil, and then measure.

- Prevent severe vibration and shock, and avoid striking the sensor with hard objects.

- Since the sensor is encapsulated in black, exposure to strong sunlight may cause the temperature to rise (up to 50°C or higher). To prevent temperature-related measurement errors, shield the sensor from direct sunlight and provide protection when used in the field or outdoors.

This NBL-S-TM soil temperature and humidity sensor combines advanced technology and strict quality control, designed to provide users with the most reliable soil environment monitoring solution. Whether it's for research projects or daily agricultural management, it provides the data support you need and is ideal for accurate soil monitoring.
