About - LoRa Soil Moisture Sensor
The Renke LoRa soil moisture sensor is a simple and inexpensive smart farming solution. It can simultaneously monitor soil temperature and moisture conditions. The monitoring data is wirelessly transmitted to the LoRa gateway through LoRa, and the LoRa gateway uploads the data of all measuring points to the cloud platform in a unified manner. Thereby easily creating a low-cost wireless remote monitoring network. Suitable for smart farm applications, irrigation, agriculture, etc.
Description
This LoRa soil moisture sensor consists of a stainless steel soil probe and a data collector. When using, insert the probe of the soil sensor into the soil, and then the data collector collects the measured value and transmits it through LoRa. The data collector is powered by a replaceable lithium sub-battery with low power consumption. Long using life. The shell is made of waterproof ABS material, and the protection level is IP65, which can be used in the outdoor environment.
Features
- The LoRa soil moisture sensor adopts LoRa spread-spectrum communication technology, featuring long transmission distance and strong anti-interference capability. The communication range can reach up to 3000 meters in line-of-sight conditions.
- The collector is equipped with a replaceable 3.6V li-Ion battery. It can monitor battery level, signal strength, and sensor data in real time, upload the information via LoRa wireless communication.
- With an IP65 protection rating, the collector is suitable for outdoor.
- The LoRa soil sensor offers high measurement accuracy, fast response speed, and good interchangeability. It is minimally affected by soil salinity, making it suitable for various soil types.
- The sensor is fully sealed, resistant to acid and alkali corrosion, and capable of long-term dynamic monitoring when buried in soil. The LORAH series supports extended transmission distance by adding LoRa intermediate repeaters.

How to install LoRa soil moisture sensor?
Site selection
The collector should be placed as high as possible and in a relatively open place around it. It is recommended to be more than 1 meter above the ground. Do not place too many metal objects around the LoRa soil moisture sensor to prevent the wireless signal from being weakened. Electronic interference can originate from a variety of objects: generators, high-current equipment, high-voltage relays, transformers, etc. Vibration or shock can also be a source of interference, so the sensor should be installed as still as possible.
Do not install the LoRa soil moisture sensor in an environment beyond the measurement range, otherwise, the product will not work properly and the sensor will be permanently damaged. Please do not tear off the label on the product casing, which has important information such as the product’s ID.
Installation process
When installing the collector, first open the housing and insert the universal plug-in li-Ion battery (note: do not pull forcefully when opening the housing to avoid damaging internal wiring). The battery should be placed above the circuit board (note: if purchasing a battery separately, pay attention to the wiring of the connector). The indicator light will flash rapidly and then turn off once the process is complete. Reinstall the housing (ensure there are no visible gaps between the upper and lower casing to maintain waterproofing). Screw the antenna provided by our company onto the device.
For LORAH series products, users must first install the fuse holder into the designated interface. Once installed, the device will be powered on. Then, screw the antenna provided by our company onto the device
FAQs - LoRa Soil Moisture Sensor
What is a LoRa soil moisture sensor?
A LoRa soil moisture sensor is a wireless device that measures soil water content and transmits data over a long range using LoRa (Long Range) communication technology. It is ideal for smart farming and remote irrigation monitoring.
How to configure the collector of LoRa soil moisture sensor?
Configuration via mobile phone NFC. Turn on the NFC function of the mobile phone, put the mobile phone against the surface of the collector, and configure it after the connection is completed.
What should I pay attention to when using the LoRa soil moisture sensor?
- The steel probs must be fully inserted into the soil when measuring.
- Avoid strong sunlight directly on the sensor and cause the temperature to be too high. Pay attention to lightning protection when used in the field.
- Do not bend the steel needle violently, do not pull the sensor lead wire forcibly, and do not drop or violently hit the sensor.
- The sensor protection level is IP68, and the sensor can be immersed in water (the collector cannot be directly immersed in water).
- The sensor and the LoRa soil collector are connected by a plug-in cable. Please use the correct plug-in method when plugging.
How to install the LoRa soil sensor?
Method 1: Select a suitable measurement location, avoid stones, ensure that the steel needle does not touch hard objects, discard the topsoil according to the required measurement depth, maintain the original tightness of the soil below, and firmly hold the sensor and insert it vertically The soil should not be shaken left and right when inserting. It is recommended to measure multiple times within a small range of a measuring point to obtain an average value.
Method 2: Dig a pit with a diameter > 20cm vertically, insert the sensor steel needle into the pit wall horizontally at a given depth, the collector cannot be buried in the soil, and the pit should be filled tightly and stabilized for a period of time. , measuring and recording for months or longer.
