Description

The Seeed Studio SenseCAP S2105 is a battery-powered wireless LoRaWAN® soil sensor that simultaneously measures soil moisture (volumetric water content), soil temperature, and electrical conductivity (EC) using FDR sensing — the essentials for precision irrigation and crop health.

Soil EC indicates salinity and influences nutrient availability and microbial activity, so the S2105 gives a fuller picture than moisture alone. With up to 10-year battery life, an IP66 enclosure rated −40 °C to +85 °C, and 2–10 km LoRaWAN range, it's built for harsh outdoor agriculture — and sets up in minutes via Bluetooth, no tools or wiring required.

Core Capabilities

3-in-1 Soil Sensing (Moisture, Temp, EC) FDR soil moisture (0–100% VWC, ±3%), temperature (−40 to +80 °C, ±0.5 °C), and electrical conductivity (0–23 dS/m, ±5%) — measuring water, heat, and salinity for smarter irrigation and fertigation.
Long-Range LoRaWAN, One Global SKU Built on the Wio-E5 (LoRaWAN v1.0.3 Class A) with 19 dBm Tx and −136 dBm sensitivity for 2 km urban / 10 km line-of-sight range. A single SKU supports 7 frequency plans (EU868, US915, AU915, AS923, KR920, IN865, RU864).
10-Year Battery & Rugged IP66 A replaceable D-size ER34615 Li-SOCl₂ battery (19 Ah) gives up to 10 years of operation. The IP66 enclosure (−40 to +85 °C) shrugs off UV, heavy rain, and dust, with a 5 m soil-probe cable for flexible burial depth.
No-Code Bluetooth Setup Built-in Bluetooth lets you configure and update the sensor in four steps using the free SenseCAP Mate app — no programming. Validated through six reliability tests for dependable performance in extreme conditions.

Typical Applications

Precision Agriculture & Irrigation: Schedule irrigation and fertigation from real soil moisture and EC data to save water, boost yield, and avoid over/under-watering across fields.
Greenhouses & Horticulture: Monitor root-zone moisture, temperature, and salinity to optimise growth and nutrient delivery in controlled environments.
Turf, Landscaping & Sports Fields: Maintain healthy turf and green spaces with data-driven watering and salinity management.
Environmental & Research Monitoring: Build distributed soil-monitoring networks for hydrology, climate, and land-management research with long-range, low-maintenance sensors.

Technical Integration

Key points for adding the S2105 to your LoRaWAN network:

Connectivity: LoRaWAN® v1.0.3 Class A; a single global SKU supporting 7 frequency plans (863–928 MHz: EU868, US915, AU915, AS923, KR920, IN865, RU864).
Network server & platform: Works with any standard LoRaWAN gateway and network server (e.g. The Things Stack, ChirpStack) or the SenseCAP platform.
Configuration: No-code Bluetooth setup via the free SenseCAP Mate app; the frequency plan is set on first power-up and can be changed any time.
Power: Pre-installed, replaceable D-size ER34615 Li-SOCl₂ battery (19 Ah) for up to 10 years of operation.
Probe & environment: 5 m soil-probe cable, 405 g; IP66 enclosure rated −40 °C to +85 °C for UV, rain, and dust.
Setup help: For frequency/gateway selection or deployment support, contact the shopioT technical team.

Frequently Asked Questions

What does the S2105 measure, and why does EC matter?

Soil moisture (0–100% VWC), temperature (−40 to +80 °C), and electrical conductivity (0–23 dS/m). EC reflects soil salinity, which affects nutrient availability, microbial activity, and crop yield — so you manage fertigation and salt build-up, not just water.

Does it need a LoRaWAN gateway?

Yes. It transmits over LoRaWAN to a gateway and network server (The Things Stack, ChirpStack, or a Milesight/SenseCAP gateway). A gateway is sold separately.

Which frequency plan does it use?

A single device supports 7 plans (EU868, US915, AU915, AS923, KR920, IN865, RU864). It ships unset and is configured on first power-up via Bluetooth — and can be switched at any time.

How long does the battery last, and is it replaceable?

Up to 10 years on a replaceable D-size ER34615 Li-SOCl₂ battery (19 Ah). Actual life depends on reporting interval, payload, and distance to the gateway.

How is it configured?

No-code setup in four steps via Bluetooth using the free SenseCAP Mate app — no programming required.

Is it suitable for outdoor / harsh conditions?

Yes. It's IP66-rated for −40 to +85 °C and passed six reliability tests (high/low temperature, conformance, waterproof, freezing, long-range, and production), making it suitable for UV, rain, and dust.
