• Simple Configuration: SenseCAP provides a no-code experience that enables users to finish configuration with 4 steps through SenseCAP Mate APP, making deployment of the S2105 Soil Moisture Temperature EC Sensor simple and efficient.

High-performance Guarantee

We are well aware that the sensors may work under harsh outdoor conditions. To ensure that the performance and durability of the Seeed Studio SenseCAP S2105 LoRaWAN Soil Moisture Temperature EC Sensor are consistent with their specifications throughout the complete lifecycle, SenseCAP S210X went through 6 reliability tests before releasing and met the requirements to perform perfectly in extreme conditions.

• High-Low Temperature Test – determine performance under adverse temperature conditions.
• Conformance Test – whether the collected values of multiple S2105 Soil Moisture Temperature EC Sensors are consistent.
• Waterproof Test
• Freezing Test
• Long-Range Communication Test – whether the device loses packets under long-distance LoRaWAN transmission.
• R&D and Production Test – to test the pass rate of multiple Seeed Studio SenseCAP S2105 sensors under factory conditions.

Specification

* Every single Seeed Studio SenseCAP S2105 Soil Moisture Temperature EC Sensor device can support 7 frequency plans.

** This wireless S2105 LoRaWAN Soil Moisture Temperature EC Sensor supports up to 10 years of battery life, but the actual battery life varies from data upload interval, data payload, and distance between gateways.

*** We have updated the battery lifetable, which should provide you with a better estimate of the actual battery life of your SenseCAP S2105 LoRaWAN Soil Moisture Temperature EC Sensor. We recommend that you refer to the updated table when making any judgment or decision related to the battery life of your device.

LoRaWAN Frequency

Note: No Frequency limitation. The Seeed Studio SenseCAP S2105 Soil Moisture Temperature EC Sensor can be switched to other LoRaWAN frequency plans at any time.

S2105 Devices are manufactured by Seeed Studio SenseCAP to support the universal LoRaWAN frequency plan from 863MHz ~928MHz in one SKU. That is to say, every single Soil Moisture Temperature EC Sensor can support the frequency plans below:

The frequency plan setting is none by default and the SenseCAP S2105 Soil Moisture Temperature EC Sensor will not transmit RF signal until it has been set by App via Bluetooth at the first power-up. And it can be changed to other LoRaWAN frequency plans at any time.

Hardware Overview

Seeed Studio SenseCAP S2105 LoRaWAN Soil Moisture Temperature EC Sensor measures moisture, temperature and EC at the range of 0 ~ 100% (m/m), -40 ~ 80, and 0 to 23 dS/m respectively. Soil electrical conductivity (EC) is a metric of the salt content in the soil which will affect crop yield and quality, plant nutrient availability, and the activity of soil microbes. S2105 Soil Moisture Temperature EC Sensor can be widely applicable in soil sensing scenarios. It is specifically optimized for OTA with built-in Bluetooth, which enables quick setup and update. Benefiting from LoRaWAN and IP66 design, this Seeed Studio SenseCAP S2105 features stability and reliability and can cover a long transmission range while keeping lower power consumption. Unlike wireline devices, it is battery-powered, reducing the workload and complexity of the deployment, and can be disassembled and installed in a few minutes.

It can cover a transmission range of 2km in urban scenes and 10km in line-of-sight scenes while keeping lower power consumption during the transmission process. Together with a replaceable battery that supports up to 10 years of usage and an industrial IP66 enclosure, the SenseCAP S2105 LoRaWAN Soil Moisture Temperature EC Sensor supports -40 ~ 85 operating temperature and can be deployed in harsh environments.
