Note: 

Make sure the sensor is mounted vertically and not lying down on a flat surface. This will 

insure optimum reception.

Wireless

 

Reception

 

Considerations

 

Wireless signals are impacted by distance, interference (other weather stations, wireless phones, 
wireless routers, TVs and computer monitors), and transmission barriers, such as walls. In general, 
wireless signals will not penetrate solid metal and earth (down a hill, for example).   
 
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction 
decreases the transmission range by the factor shown below. 
 

Medium 

RF Signal Strength Reduction 

Glass (untreated) 

5-15% 

Plastics 10-15% 
Wood 10-40% 
Brick 10-40% 
Concrete 40-80% 
Metal 90-100%
