RXW-SMD-xxx HOBOnet Soil Moisture 10HS Sensor The HOBOnet Wireless Soil Moisture Sensor integrates the fieldproven 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 HOBOlink, Onset's innovative cloud-based software platform. Product Numbers: RXW-SMD-900 RXW-SMD-868 RXW-SMD-922 RXW-SMD-921 Key Advantages: 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
