Soil moisture and temperature are two important environmental parameters in planting while soil EC (electrical conductivity) is a key variable that indicates nutrient availability and loss. EC is related to the plant's physiology, growth, and quality. SenseCAP wireless LoRaWAN 3-in-1 sensor can measure these three factors at the same time to make gardening/farming/agriculture solutions smart and lightweight. 


S2105 wireless soil moisture, temperature, and EC sensor is based on FDR technology with advantages of simple, safe, fast, and accurate, long-term measurement, wide range, and simple calibration. It is a kind of soil moisture measurement instrument worth recommending.

Scan-and-Play Simplicity, Easy Configuration via Bluetooth in Just 1 min 

Built-in Bluetooth avoids time-consuming configuration works to bring no code experience to individuals with less or no technical background to quickly get started with CO2, temperature, and humidity sensing detection.

Minimal Maintenance Cost: power-conscious battery, IP66 rugged enclosure, and Bluetooth for remote data acquisition and device management

This sensor can cover a transmission range of 2km in urban scenes and 10km in line of sight scenes while keeping the transmission process low power to support years of usage. Remote monitoring can also benefit large-scale deployment, it gives you the biggest efficiency by saving time and manual labor needed to deploy and manage devices. Together with a replaceable battery that supports Max.10 years of usage and an industrial IP66 enclosure, it meets the need of LoRaWAN-based IoT Solutions in the real world. 

Powerful SenseCAP Mate App: data visualization and remote device management

Compatibility with multiple networks and platforms: easily integrate with existing LoRaWAN networks

We have an article in Learn to introduce the separate network architecture when you choose different LoRaWAN network servers and platforms. 

How to Select Gateway:

LoRaWAN network coverage is required when using sensors, there are two LoRaWAN network options.

Option 1: Sensors work in areas covered by Helium Network(Check on Helium Explore Map).

Option 2: Sensors work in a standard LoRaWAN network, like The Things Network, Loriot, Chirpstack, etc.

SenseCAP Performance Guarantee: robustness and stability

Tips: The battery is a standard Li-SOCl2 battery (type: ER34615) that can purchase from Amazon and other platforms.

Multi-Scenario Application

  • Agriculture Irrigation

By preventing plant stress days to improve yields and keep nutrients in the fibrous root zone, the senor enables optimal timing for effective irrigation. It uses metal probes to measure conductivity and soil moisture, demonstrating sensor's high sensitivity and low detection limits.

  • Greenhouse and Garden Planting

The EC of the soil temperature and humidity are important conditions that affect the environment in the root zone of greenhouse plantings. The sensor helps gain control over the root zone environment of the greenhouse by making irrigation decisions. If applied properly, it can significantly improve the yield and reduce the cost of greenhouse growing.

  • Turf and Lawn Management

The concept of soil moisture monitoring is now being applied to turf management. Salt problems in turfgrass can be difficult to manage since the soluble salts in the soil restrict plant growth. The sensor, used by industry's turf professionals and council turf managers, can achieve actual savings and benefits.

  • Drought Monitoring

Planting, irrigation, and land management increase soil salinity levels and occur naturally in arid and semi-arid climates. Such droughts can affect the economy and even lead to a regional famine. Thus, the sensor can accurately predict and characterize harmful droughts.
