DAVIS Temperatur/Humidity Sensor for GroWeather, EnviroMonitor, & Weather Monitor - Manual (Page 5)

Installing the T/H Sensor Page 5
Look for a location which satisfies the following requirements:
✦ Ideally, install the sensor in a Davis radiation shield.
✦ Place the sensor in a location shielded from rain and other sources of
water such as rainfall runoff.
CAUTION: It is important that no water strike the sensor.
✦ Place the sensor in a location where it will not be in direct sunlight and
where it will have limited exposure to reflected sunlight.
If possible, place the sensor at least 5 feet (1.5 m) from any surface which
is exposed to direct sunlight because the heat from this surface may
affect air temperature readings in the vicinity.
✦ Limit the exposure of the sensor to the open night sky.
If you are unsure about a location's exposure to the night sky, check for
dew at that location on a light dewy morning. If the area is dry, the loca-
tion should work well.
✦ Place the sensor in a location at least 10 feet (3 m) away from any lights
or lamps.
✦ Place the sensor at least 5 feet (1.5 m) from man-made sources of heat,
such as vents.
✦ Keep the sensor away from AC power lines.
Keep the sensor and most of the cable at least 10 feet (3 m) from 110 VAC,
60 Hz utility power. Do not run the sensor cable parallel to house wiring.
Mount the sensor at least 30 feet (9 m) from high-voltage power lines
and transformers.
✦ When running the sensor cable, try not to run it across large metal
objects (e.g., aluminum siding).
