Check the 

distance

 and 

resistance

 between the outdoor sensor and weather 

station. Outdoor sensors at the end of the range may work while batteries are 

fresh but not after they drain a bit. 

 

Check for leaking batteries, which may damage the outdoor sensor. 

 

Battery life is over 24 months when using reputable battery brands for both 

Alkaline and Lithium batteries. 

 

Outdoor sensor fell. The sensor no longer works 

 

Explanation: If there is no physical damage to the outdoor sensor, the fall may 

not have caused internal damage. A fall can shock the outdoor sensor or the 

batteries in the outdoor sensor. Batteries that have fallen on a hard surface may be 

damaged and unable to function properly. 

 

 

Complete a 

Restart

 with fresh batteries. 

 

Use 

Batteries 

dated at least six years in advance of the current year. Batteries 

dated earlier than six years from now may still work, but may be unstable in 

performance. 

Note: An outdoor sensor that has fallen into puddle, snow, or other standing water, 

will likely have water damage and need to be replaced. Outdoor sensors are water 

resistant, not waterproof.

Mounting/Positioning Outdoor sensor 

 

First: Place the outdoor sensor in the desired shaded location and the weather 

station in the home. Wait approximately 1 hour before permanently mounting the 

outdoor sensor to ensure that there is proper reception.  

 

POSITION 

Outdoor: 

 

Protect the outdoor sensor from standing rain or snow and from the overhead 

sun, which can cause it to read incorrectly.  

 

Mounting under an eave or deck rail works well. 

 

If you choose, you can construct a small roof or box for the outdoor sensor. Be 

sure a box has vents. 

 

Mount the outdoor sensor on the North side where to prevent sun from causing 

incorrect readings.  

 

Mount at least 6 feet in the air for a strong RF (radio frequency) signal. 

 

Do not mount the outdoor sensor on a metal fence. This significantly reduces 

the effective

 range

. 

 

Outdoor sensors are water resistant, not waterproof.
