Description

Product information "seeed SenseCAP S2108 Soil Moisture & Temperature Sensor, LoRaWAN, BT, IP66, 0-100% VWC, -40-80°C, IP66"

SenseCAP S2108 Soil moisture, temperature and pore EC sensor
The SenseCAP S2108 is a sensor for the simultaneous measurement of soil moisture, temperature and electrical conductivity (pore EC). It is used for precise monitoring of soil conditions in applications such as agriculture, horticulture, greenhouse control, water management and environmental research. By combining three measurement parameters, the device enables a comprehensive assessment of soil quality and supports data-based decisions on irrigation, fertilisation and land management.

The device measures soil moisture in the range from 0 to 100 % (VWC), soil temperatures from -40 °C to 80 °C and electrical conductivity up to 32 ms/cm. The data obtained helps to control water consumption, monitor nutrient levels and analyse the salt concentration in the soil, which is crucial for plant growth.

The sensor uses LoRaWAN technology with a range of up to 10 km in free line of sight and around 2 km in urban environments. The IP66-certified housing offers protection against dust and water and is suitable for extreme outdoor use. The Bluetooth interface in conjunction with the SenseCAP Mate app allows easy setup and remote configuration without specialised technical knowledge. It is powered by a replaceable ER34615 battery (D-size) with up to 10 years of operation.
The SenseCAP S2108 is designed for use in automated and long-term monitored irrigation systems. Typical applications include the precise control of water supply in agriculture, moisture monitoring in greenhouses, drought detection in open landscapes and the long-term collection of soil parameters in environmental research.

The device measures the moisture content in the soil, the temperature and the salt content based on the electrical conductivity. This information helps to assess soil quality and organise the water supply efficiently. The sensor can also indicate changes in the nutrient balance, which can be measured by the EC value (electrical conductivity). In simple terms, the sensor recognises how wet the soil is, how warm it is and how many salts are in it. This enables targeted irrigation and fertilisation.
