Brand:Onset Model No:RXW-SMD-900 Our Model No:RXWSMD900
Product Overview
Features
Sensor:
Measurement range: In soil: 0 to 0.570 m3/m3 (volumetric water content)
Extended range -0.659 to 0.6026 m3/m3
Accuracy: ±0.033 m3/m3 (±3.3%) typical 0 °C to 50 °C (32 °F to 122 °F) for mineral soils up to 10 dS/m and ±0.020 m3/m3 (±2%) with soil specific calibration
Resolution: 0.0008 m3/m3 (0.08%)
Volume of influence: 1 liter (33.81 oz)
Sensor frequency: 70 MHz
METER ECH2O Probe Part No.: 10HS
Operating temperature range: 0 °C to 50 °C (32 °F to 122°F); Although sensor probe and cable can safely operate at below-freezing temperatures (to
40 °C/°F), soil moisture data collected at these extreme temperatures is outside of sensor's accurate measurement range; Extended temperatures above 50
C (122 °F) will decrease mote battery life
Wireless Mote:
Operating temperature range: -25° C to 60 °C (-13 °F to 140 °F) with rechargeable batteries; -40 °C to 70 °C (-40 °F to 158 °F) with lithium batteries
Radio power: 12.6 mW (+11 dBm) non-adjustable
Transmission range: Reliable connection to 457.2 m (1,500 ft) line of sight at 1.8 m (6 ft) high; Reliable connection to 609.6 m (2,000 ft) line of sight at 3 m (10 ft) high
Wireless data standard: IEEE 802.15.4
Radio operating frequencies: 904 MHz to 924 MHz
Modulation employed: OQPSK (Offset Quadrature Phase Shift Keying)
Data rate: Up to 250 kbps, non-adjustable
Duty cycle: < 1%
Maximum number of motes: 50 motes per one RX Wireless Sensor Network
Battery type/Power source: Two AA 1.2V rechargeable NiMH batteries, powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40 °C to 70 °C (-40 °F to 158 °F)
Memory: 16 MB
Sensor materials: Weatherproof
Mote materials: PCPBT, silicone rubber seal
Environmental rating: IP67, NEMA 6
Environments: Outdoor
Measurements: Soil Moisture Description
The Onset HOBO RXW-SMD-900 HOBOnet Wireless Soil Moisture 10HS Sensor measures soil moisture and is designed to work with the HOBOnet Wireless Sensor Network, in which data is transmitted wirelessly from the sensor mote across the network to an RX3000 station and then uploaded to HOBOlink web-based software. With HOBOlink, you can monitor sensor readings, view graphs, set up alarms, download data, and more.
