HOBO MicroRX Station
Overview
With two power options available (a solar panel for extended deployments or user-replaceable batteries for flexible mounting in covered or protected locations), this monitoring station includes inputs for up to five of our research-grade plug-and-play sensors. (Sensors must be purchased separately.)
Configurable station-side alarms trigger immediate notifications of critical conditions, and LI-COR Cloud (formerly HOBOlink) platform makes it easy to view, access, and share data. This station can also be ordered with an additional water level sensor input with integrated flow conversion.

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, RX2104 and RX2106: 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
RX2101, RX2103 and RX2105: 6 AA 1.5 V lithium batteries or AC power adapter (P-AC-1)
Battery Life
RX2102, RX2104 and RX2106 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
- RX2106: 3 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.
RX2105 Battery Life:
Runs continuously with the included AC adapter. Batteries can be used as a backup to AC power; battery life of 3 months with 1 minute logging and daily connections or 2 months with 1 minute logging and hourly connections, and with approximately 10 motes. Note: Deployments in areas with weak cellular strength could reduce battery life.
