Silicon Pyranometer Smart Sensor (Part # S-LIB-M003)

The Silicon Pyranometer smart sensor is designed to
work with the HOBO

®

Weather Station logger. The
smart sensor has a plug-in modular connector that
allows it to be added easily to a HOBO Weather
Station. All calibration parameters are stored inside
the smart sensor, which automatically communicates
configuration information to the logger without the
need for any programming, calibration, or extensive
setup.

Mounting

Accessories

• Light Sensor Mounting Bracket (Part # M-LBB)

• Light Sensor Level (Part # M-LLA)

Bracket Mounting

It is recommended that you mount the Silicon Pyranometer smart sensor with the light sensor bracket on a
pole or tripod (see Figure 1). To mount the sensor using the bracket:

1. Attach the light sensor bracket to a 1¼ inch to 1

Note: The bracket can also be mounted on a flat, vertical surface using four screws.

2. Position the Silicon Pyranometer sensor on top of the bracket with its cable running through the

slot in the bracket.

3. Using the two screws supplied, attach the sensor to the bracket through the two holes on either

side of the slot.

Note: Do not completely tighten the screws until you level the sensor.

5

/8 inch pole with the provided U-bolts.

4. Position the bracket so it faces toward the equator, minimizing the chance of shading.

5. Mount the bracket on the mast with the two U-bolt assemblies, mounting it high enough on the

mast to avoid the possibility of shading the sensor.

Note: If you mount the sensor above eye level, use a step ladder or other secure platform when
leveling the sensor so that you can clearly view the Light Sensor Level (Part # M-LLA).
