Showing 1 - 10 of 10 products

Modern farming benefits from precise data directly from the ground—in real time and without manual on-site checks. With LoRaWAN soil sensors from Dragino, you can monitor soil moisture, pH value, leaf wetness, and soil temperature wirelessly across large areas. The sensors reliably transmit their measurement data over several kilometers via LoRaWAN. This setup is energy-efficient, low-maintenance, and compatible with common IoT platforms such as TTN and Chirpstack.

Which LoRaWAN Agricultural Sensors are in the Assortment?

Our assortment includes specialized Dragino soil sensors for various agronomic measurement variables:

Soil Moisture & EC Value The Dragino SE01 and SE0X sensors simultaneously measure volumetric soil moisture and the electrical conductivity (EC value) of the soil. The EC value provides insights into salinity and nutrient concentration in the soil, making it a crucial parameter for fertilizer planning. Solar-powered variants (LS models) enable completely grid-independent operation.

Soil pH Value The Dragino SPH01 measures the pH value directly in the soil. It is available as a battery-powered (LB) or solar-powered (LS) variant and is perfectly suited for long-term outdoor use in fields.

Leaf Wetness The Dragino LMS01 detects wetness on leaf surfaces—highly relevant for identifying fungal diseases and optimally controlling crop protection measures. A solar-powered variant is available here as well.

Soil Temperature The Dragino D20S measures the temperature in the soil and on road surfaces via a ground probe. It is suitable for both agricultural and infrastructural applications, such as frost early-warning systems.

Multi-Segment Soil Sensor The Dragino GroPoint Air captures soil moisture and temperature across multiple depth layers simultaneously. It is ideal for detailed soil profiles in research and precision agriculture.

Measuring LoRaWAN Soil Moisture: How the System Works

A LoRaWAN soil moisture sensor consists of two components: the sensor itself, which records the measurement values in the ground, and the LoRaWAN wireless module, which transmits the data wirelessly to a gateway. From there, the data reaches an IoT platform or goes directly into your agricultural software.

The workflow in practice:

Sensor is placed in the soil at the desired depth
Measurement values are recorded at configurable intervals
Transmission via LoRaWAN to a gateway (range: several kilometers)
Evaluation in real time via TTN, Chirpstack, or other platforms
Automated response: e.g., triggering the irrigation system when a threshold value is breached

FAQ – Frequently Asked Questions About LoRaWAN Soil & Agricultural Sensors

Here, we answer some questions about our LoRaWAN soil and agricultural sensors. If you would like a personalized consultation, please contact us via our contact form.

What does a LoRaWAN soil sensor measure?

Depending on the model, the sensors measure volumetric soil moisture, electrical conductivity (EC value), pH value, soil temperature, or leaf wetness. Some models, like the Dragino SE01, record multiple parameters simultaneously.

How far does a LoRaWAN agricultural sensor transmit data?

LoRaWAN typically allows for ranges of 2–5 km in open fields, and even significantly more under optimal conditions. This means even extensive agricultural areas can be covered with a single gateway.

Do I need my own LoRaWAN network?

You need a LoRaWAN gateway within range. Alternatively, you can use public networks like The Things Network (TTN), provided there is coverage in your region. EXP-Tech also offers suitable LoRaWAN gateways.

Are the sensors suitable for long-term outdoor use?

Yes. The Dragino agricultural sensors are designed for outdoor use and are built to be appropriately weatherproof. Solar-powered models (LS variants) are particularly low-maintenance, as no battery changes are necessary.

What is the EC value and why is it relevant for agriculture?

The EC value (electrical conductivity) provides information about the salinity and nutrient concentration in the soil. An EC value that is too high can inhibit plant growth, while a value that is too low indicates a nutrient deficiency. In combination with soil moisture, it provides a solid foundation for precise fertilizer planning.

What is a leaf wetness sensor and what is it used for?

A leaf wetness sensor like the Dragino LMS01 measures the moisture on the surface of plant leaves. Long periods of leaf wetness favor fungal diseases such as powdery mildew or Botrytis. With a leaf wetness sensor, the optimal timing for crop protection measures can be precisely determined, reducing the use of fungicides.
