1. Introduction

Thanks for purchasing this WH31 wireless

thermometer and hygrometer sensor. This

device measures temperature and

humidity and supports up to 8

channels(one unit for one channel,

optional sensors sold separately). The

data can be streamed by GW1000 Wi-Fi

Gateway(sold separately) and can be

viewed on our WS View mobile application

after the Wi-Fi configuration done.

To ensure the best product performance,

please read this manual and retain it for

future reference.

units and channel number:

Temperature Units: To change the

transmitter display units of temperature

measure (°F vs. °C), change Dip Switch 4,

as referenced in Figure 3.

Channel Number: This device supports

up to eight sensors. To set each channel

number, change Dip Switches 1, 2 and 3,

as referenced in Figure 4.

Switch in down position. Switch in

3.Insert two AA batteries.

4.Verify the correct channel number (CH)

and temperature units of measure (°F

vs. °C) are on the display.

5.Close the battery door.

Repeat for the additional remote

transmitters(sold separately), verifying

each remote is on a different channel.

5. Sensor Placement

The best mounting location for the indoor

sensor is in a location that never receives

direct sunlight, not even through windows.

Also, do not install in a location where a

nearby radiant heat source (radiator,

heaters, etc.) will affect it. Direct sunlight

and radiant heat sources will result in

inaccurate temperature readings.

The unit is weatherproof, but besides

heeding the placement instructions above,

you should also attempt to mount the unit

under cover (eve or awning or similar).

To mount or hang the unit on a wall or

wood beam:

Use a screw or nail to affix the remote

sensor to the wall, as shown on the left

side of figure 5, or

9

Hang the remote sensor using a string,

as shown in right side of figure 5.

Figure 5: Indoor sensor mounting

Note: Make sure the sensor is mounted

vertically and not lying down on a flat

surface. This will insure optimum reception.

Wireless signals are impacted by distance,

interference (other weather stations,

wireless phones, wireless routers, TVs and

computer monitors), and transmission

10

barriers, such as walls. In general,

wireless signals will not penetrate solid

metal and earth (down a hill, for example).

6. Setup Guide (using with Wi-Fi

gateway)

If you want to view the multi channel

sensor data on your mobile application,

you need to pair this device with our

GW1000 Wi-Fi Gateway(sold separately).

6.1 Pair with Gateway

If the GW1000 has been in operation, and

you have never had any WH31

multi-channel temperature and humidity

sensor(s) setup before, just power up the

sensor(s) and GW1000 will pick

multi-channel temperature and humidity

data automatically.
