Outdoor sensors are water resistant, not waterproof.  

 

Indoor:

  

 

Mount the Outdoor Sensor indoors to monitor high mold risk areas like in a crawl space 
or a basement.

 

 

Indoor or Outdoor: 

 

Mount outdoor temperature sensor 

vertically

.  

 

Avoid more than one wall between the outdoor sensor and the weather station. 

 

The maximum transmitting range in open air is over 300 feet (91 meters).  

 

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce 
the range.  

 

Do not mount near electrical wires, transmitting antennas or other items that will 

interfere 

with the signal. 

 

RF (radio frequency) signals do not travel well through moisture or dirt. 

 

MOUNT 
Option 1: 

 

Install one mounting screw (not included) into a wall. 

 

Place the outdoor sensor onto the screw (hanging hole on the backside). 

 

Gently pull down to lock the screw in place.  

 
Option 2:    

 

Insert the mounting screw through the front of the outdoor sensor and into the wall.  

 

Tighten the screw to snug (do not over tighten). 

 

Position Weather Station 

 

 

The weather station has a pull out stand to sit on a desk or table or can be wall 
mounted.  

 

Place within 

range 

of the outdoor sensor.  

 

The maximum transmitting range in open air is 300 feet (91 meters).  

 

Obstacles such as walls, windows, stucco, concrete and large metal objects can reduce 
the range. 

 

Choose a location 6 feet or more from electronics such as cordless phones, wireless 
gaming systems, televisions, microwaves, routers, baby monitors, etc., which can 
prevent signal reception. 

 

Be aware of electrical wires and plumbing within a wall. This will interfere with RF (radio 
frequency) signal reception. 
 

Distance/Resistance/Interference 

 

Distance:  

 

The maximum transmitting range in open air is over 300 feet (91 meters) between the 
outdoor sensor and the weather station. This range is in open air with ideal conditions. 

 

Consider what is in the signal path between the weather station and the outdoor sensor. 

 

Avoid placing electronics in the signal path between the weather station and the outdoor 
sensor. 

 
Resistance:  

 

Obstacles such as walls, floors, windows, stucco, concrete and large metal objects can 
reduce the range.  

 

When considering the distance between the outdoor sensor and the weather station (200 
feet open air), cut that distance in half for each wall, window, tree, bush or other 
obstruction in the signal path.   

 

Closer is better.
