The transmission range of the remote temperature/humidity sensor may
be affected by the ambient temperature. At cold temperatures the
transmitting distance may be decreased. Please bear this in mind when
placing the transmitter.
The remote temperature sensor should be placed in a dry, shaded area.
The remote temperature sensor has a range of 330 feet. Keep in mind
that the 330 feet is in open air with no obstructions and that radio waves
DO NOT curve around objects. Actual transmission range will vary
depending on what is in the path of the signal. Each obstruction (roof,
walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in
half.
Example: A wireless weather station receiver with a 330 feet range is
mounted on an interior wall, so that the signal has to pass through one
interior wall, one exterior wall, and across the 10 foot width of the room
between the 2 walls. The first wall will reduce the range to 165 feet, and
the second wall will reduce the range to 87 feet. Factoring in the 10 foot
room, this leaves a maximum of 77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-metallic
siding; however certain materials can reduce range even further. Metal
siding, stucco, and some types of glass can reduce signal range by as
much as ¾ or more, compared to the ½ reduction typical of most
obstructions. It is possible to receive a signal through these materials,
however maximum range will be much less due to their tendency to
absorb or reflect a much larger portion of the sensor’s signal.
If the outdoor temperature and humidity data are not being received
within 2 minute after setting up (or the outdoor display show “--.-“ in the
outdoor section of the intelligent weather station after
failed attempts during normal operation). Please check the following
points:
1. The distance of the intelligent weather station or remote
temperature/humidity sensor should be at least 3 to 6 feet (1.5 to
2 meters) away from any interfering sources such as computer
monitors or TV sets.
2. Avoid positioning the intelligent weather station onto or in the
immediate proximity of metal doors or window frames.
