HOBO® MicroRX Station (RX2101, RX2102, RX2103 & RX2104) Manual
23808-E
The HOBO MicroRX Station provides continuous logging for a broad range of weather monitoring
and microclimate applications with up to five plug-and-play smart sensor inputs. In addition, the
HOBO MicroRX Water Level Station supports an easy-to-install water level sensor and integrated
flow conversion for monitoring streams, lakes, wetlands, tidal areas, groundwater, and more.
Logged data from the station is transferred at regular connection intervals to HOBOlink® web-
based software where you can check the latest conditions, view graphs, configure sensors and
alarms, set up a dashboard, download your data, or schedule data delivery via email or FTP. Inside
its weatherproof enclosure, this compact station has a built-in LCD screen to check the current
system configuration and status, start and stop logging, add and remove smart sensors, and
connect to HOBOlink on demand. The station offers two primary power source options depending
on your deployment needs: the RX2101 and RX2103 models include user-replaceable AA lithium
batteries while the RX2102 and RX2104 models are designed with a built-in solar panel and
rechargeable NiMH battery pack.

Battery Life
RX2102 and RX2104:
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 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.
