Onset MicroRX S Specifications

RX2100 Data Logger

MicroRX Station

The compact and rugged HOBO MicroRX Station is an easy-to­deploy, 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-and­play sensors, and can be ordered with an additional water level
sensor input with integrated flow conversion. Configurable station­side alarms trigger immediate notifications of critical conditions, and
Onset’s cloud-based HOBOlink platform makes it easy to view,
access, and share data.

Supported 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

Battery Life

RX2101 and RX2103: -40° to 60°C (-40° to 140°F)
RX2102 and RX2104: -20° to 60°C (-4° to 140°F)

100 m (328 ft) maximum

Maximum of 15 (some smart sensors use more than one data channel; see sensor manual
for details)

±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

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
RX2101 and RX2103: 6 AA 1.5 V lithium batteries or AC power adapter (P-AC-1)

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

Enclosure Access Hinged door secured by two latches with eyelets for use with user-supplied padlocks
