MOUNTING
Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We
recommend that you mount the temperature sensor on an outside North-facing wall
(under the eve of a house is ideal). 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
