The compact and rugged HOBO MicroRX Station is an easy-to-deploy, low-cost cellular solution for long-term, reliable field monitoring. Two power source options are available: a solar panel for extended deployments, and user-replaceable batteries for flexible mounting in covered or protected locations. The station includes inputs for up to five of Onset’s research-grade plug-and-play sensors, and can be ordered with an additional water level sensor input with integrated flow conversion. Configurable station-side alarms trigger immediate notifications of critical conditions, and Onset’s cloud-based HOBOlink platform makes it easy to view, access, and share data.

In what environment does this data logger operate?
This data logger operates in an outdoor environment.
What measurements does this data logger support?
The RX2100 data logger supports the following measurements: Absolute Pressure, 4-20mA, AC Current, AC Voltage, Amp Hour (Ah), Barometric Pressure, DC Voltage, Evapotranspiration, Kilowatt Hours (kWh), Leaf Wetness, Light Intensity, PAR, Power Factor (PF), Pulse Input, Rainfall, Relative Humidity, Soil Moisture, Temperature, Volt-Amp Reactive hour, Volt-Amps (VA), Water Level, Watt Hours (Wh), Watts (W) and Wind
Operating Range： RX2101 and RX2103: -40° to 60°C (-40° to 140°F)
RX2102 and RX2104: -20° to 60°C (-4° to 140°F)
Smart Sensor Connectors： 5
Smart Sensor Network Cable Length： 100 m (328 ft) maximum
Smart Sensor Data Channels： Maximum of 15 (some smart sensors use more than one data channel; see sensor manual for details)
Logging Rate： 1 minute to 18 hours
Time Accuracy： ±8 seconds per month in 0° to 40°C (32°F to 104°F) range;
±30 seconds per month in -40° to 60°C (-40° to 140°F) range
Battery Type/Power Source ： RX2102 and RX2104: Integrated 1.7 watt solar panel and NiMH rechargeable battery pack; optional AC power adapter (P-AC-1) or external solar panel (SOLAR-xW) can be used in place of integrated solar panel

Battery Life
RX2102 and RX2104 Battery Life:
Typical 3–5 years when operated in the temperature range -20° to 40°C (-4° to 104°F); operation outside this range will reduce the battery service life.
Maximum connection rates with built-in solar panel, in full sun:
• 10 minute connections year round for latitudes less than ±40°
• 10 minute connections through three seasons in other regions, reduced to 30 minute connections in winter
Maximum connection rates with external 5W or 15W solar panels:
• 10 minute connections year round, in full sun
• Connection rate with external solar panels may be less if deployed in partial sun
Battery life without solar recharging, with hourly connections and
1 minute logging:
• RX2102: 3 months
• RX2104: 2 months
RX2101 and RX2103 Battery Life:
Battery life with daily connections:
• RX2101: 1 year with 1 minute logging
• RX2103: 1 year with 2 minute logging
Battery life with hourly connections and 1 minute logging:
• RX2101: 3 months
• RX2103: 2 months
Note: Deployments in areas with weak cellular strength could reduce battery life.
Memory ： 16 MB, 1 million measurements, continuous logging
Alarm Notification Latency ： Logging interval plus 2–4 minutes, typical
