Thanks for purchasing this WH31 wireless
thermometer and hygrometer sensor. This
device measures temperature and humidity and
operates on one of 8 channels, meaning you can
measure eight distinct areas. The data can be
viewed on a WeatherMaster HP2550 weather
station console or can be streamed by GW1000
Wi-Fi Gateway and can be viewed on the WS
View App after configuration.

5. Sensor Place ent
The sensor is ideally mounted in a location
that never receives direct sunlight. Also, avoid
locations with a nearby radiant heat source
(radiator, heaters etc.) Direct sunlight and
radiant heat sources will result in inaccurate
temperature readings.
The unit is weather resistant. If you are
placing it outside, please select a covered,
sheltered location in the eves or under an
awning.
To mount or hang the unit on a wall or wood
beam either:
 Use a screw or nail to attach the remote
sensor to the wall, as shown in Figure 5,
-or-
