RAIN GAUGE:
RAIN: Install the Rain gauge on a level platform that is stationary. If the
gauge isn't level it will read low, and if it isn't stationary, wind will cause it to
read rain that is not falling.
Ideally the Rain sensor should have a direct line of sight to the Thermohygro
sensor.
On the bottom of the sensor there are 4 screw holes that can be used to
mount the gauge. First remove the cover. Push down and twist counter
clockwise, then pull the cover off. This will give you access to the screw
holes.
NOTE
: Be surenot to screw the rain sensor down too tightly as that will result
in a low or inaccurate reading.
TIP
: Use only 2 screws (across from each other to stabilize) that are just snug
not tight. If mounted on a piece of wood, the wood can swell when wet causing
the mounting screws to become too tight.
Place the Rain gauge 6ft (or more) above the ground. This will prevent dirt
from clogging the gauge.
NOTE
: You may need to periodically clear debris such as leaves, spider nests
etc from the rain gauge, so be sure it is accessable.
THERMOHYGRO SENSOR:
THERMOHYGRO: Place the Outdoor sensor vertically, in a well-shaded area
that is protected from direct rainfall and sun. The sensor will read high if
exposed to the sun. If the sensor gets too wet it will not read accurate
humidity. Light incidental exposure to water typically will not harm the
sensor.
See the
Distance/Resistance
cautions.
A good location is under the eaves on the north side of the house. A small
roof or box can be built for it if there is have an overhang. Please be sure it is
well vented.
Ideally the Wind & Rain sensors should have a direct line of sight to the
Thermohygro sensor. It is important that all sensors are on the same side of
the house.
It is best to mount the sensor with screws as tape can fail causing the sensor
to fall. Tape is great for positioning until the best location for the sensor to
maintain contact with the display is determined.
NOTE:
Do not place sensor in a plastic bag.
DISTANCE/RESISTANCE
Distances listed as supported on packages are based on line-of-sight testing,
which means no obstructions and optimal conditions.
Each barrier reduces the estimated distance by up to 50%.
