Introduction
The HOBO® Micro Station is a four-sensor data logger designed for
applications requiring multi-channel monitoring of microclimates in
one or more locations. Part of the HOBO Weather Station family, the
Micro Station uses a network of smart sensors for taking
measurements. Key features of the smart sensors include:
Chapter 1: Introduction
• Automatic detection upon launch
. No extensive
programming, wiring, or calibrating is required to set up
sensors.
• Easy expansion

ply by plugging them in before logging begi
sim
. Because the logger is not pre-configured, up

ns. Using an
expansion chassis, up to 15 data channels are possible.
• Digital network
. The connections between the s
m
art
sensors
and the logger are digital, ensuring accurate, reliable data collection and storage.
• Weatherproof. A silicone gasket around the edge of the case keeps out moisture, while a Gore™
Vent allows the case to breathe while also keeping moisture out.

Phillips-head screwdriver
• Slotted screw
• Pen, pencil, or other blunt instrument
• Adjustable 8 inch or 10 inc
• Utility or pocket knife
• PC interface cable (CABLE-PC-3.5) for serial ports; USB serial adapter (ADAP-SER-USB) if

6. Insert the sensor connectors through the dome nut. The threaded side of the dome nut should be
facing towards the connector. Then, slide the cables through the stuffing gland and through the
hole in the case. Push the cables into the slit insert.
Note: The electronics on some older temperature sensors are housed in a tube that is close to the
sensor connector. If you have any of these sensors, be sure to insert them first because they will
need more room inside the logger. Adjust the sensor as needed so that the tube with the
electronics fits inside the logger without too much unnecessary bending of the cable.
