OVERVIEW
Unlock Accurate Soil Moisture Data with ECH2O™ 10HS Sensor
Integrates the field-proven ECH2O™ 10HS Sensor and provides readings directly in volumetric water content. The 10cm probes measure soil moisture over a larger volume of soil, helping to average out any soil variability. The sensor’s high-frequency design minimizes sensitivity to salinity and textural effects, and gives it a wide measurement range.
HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station, or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through the LI-COR Cloud IoT platform (formerly HOBOlink).
This sensor measures soil moisture and is designed to work with the HOBOnet (HOBO® RX) Wireless Sensor Network in which data is transmitted wirelessly from the sensor mote across the network to the station and then uploaded to LI-COR’s Cloud IoT platform. With LI-COR’s Cloud IoT platform, you can monitor sensor readings, view graphs, set up alarms, download data, and more.
Features
Sensor Features
- ±3% accuracy in typical soil conditions, and ±2% accuracy with soil-specific calibration
- Measures a large 1-liter volume of soil, providing a more accurate picture of average soil moisture
- High-frequency (70 MHz) circuit provides good accuracy even in high-salinity and sandy soils.
Wireless Features
- 900 MHz wireless mesh self-healing technology
- 450 to 600 meter (1,500 to 2,000 feet) wireless range and up to five hops
- Up to 50 wireless sensors or 336 data channels per HOBO RX station
- Simple button-push to join the HOBOnet wireless network
- Onboard memory to ensure no data loss
- Powered by rechargeable AA batteries and built-in solar panel
Important Information
A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor, OR one HOBO MicroRX station (which has an integrated HOBOnet Wireless Manager) and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RXW-RPTR-xxx or RXW-RPTR-B-xxx) can be added to extend the range.

Although the sensor probe and cable can safely operate at below-freezing temperatures (to -40°C/F), the soil moisture data collected at these extreme temperatures is outside of the sensor’s accurate measurement range. Extended temperatures above 50°C (122°F) will decrease mote battery life. Wireless Mote
