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.
