STEP 3: MOUNTING BASICS

At this time, all of your sensor information should be displayed on your station. Here are a few quick tips for mounting your sensors:

THERMO-HYGRO
Keep out of direct sunlight & ensure the sensor is well-ventilated.

  • We recommend mounting under a deck or eave facing north.

MULTI-SENSOR
Ensure the sensor is mounted vertically – an unobstructed rooftop is ideal.

  • Your wind sensor should be the tallest object in the area to avoid any obstructions.
  • You may need to clean the rain funnel of debris from time to time, to avoid inaccurate rainfall readings.
  • For accurate direction, face the solar panel South.
  • For detailed sensor setup and mounting instructions, see page 18.
