INTRODUCTION
Thank you for selecting 7-Day forecast air quality WI-FI weather station. This system gathers many
advance features for weather observer, such as ProWeatherLive (PWL) cloud service which provide online
weather forecast and condition of your area onto your console while at the same time receiving your
personal weather data upload to be viewed on PWL website or PWLApp anytime. The 7-in-1 professional
wireless sensor-array integrates temperature, humidity, wind, rain, UV and light sensors together, to
continually monitoring your local weather conditions at all time and transmit these data to your console
through wireless radio frequency technology. This system also support up to 7 thermo-hygro optional
sensor(s) and other optional air quality sensors which include PM2.5/10, CO2, HCHO/VOC and CO
sensors, so you may monitor all your environment condition in one system, one app.
1. QUICK START
The following Quick Start Guide provides the necessary steps to install and operate the weather station,
and upload to the internet, along with references to the pertinent sections.

2. PRE-INSTALLATION
2.1 CHECKOUT
Before permanently install your weather station, we recommend the user to operate the weather station at
a location which is easy to access to. This will allow you to get familiar with the weather station functions
and calibration procedures, to ensure proper operation before installing it permanently.
2.2 SITE SELECTION
Before installing the sensor array, please consider the followings:
1. Batteries must be changed about every 2 to 2.5 Years
2. 
be installed at 1.5M (5’) from any building, structure, ground or roof top.
3. Choose an area of open space in direct sunlight without any obstruction of rain, wind, and sunlight.
4. Transmission range between sensor array and console could reach a distance of 150m (or 450 feet) at
line of sight, providing there are no interfering obstacles in between or nearby such as trees, towers, or
high voltage line. Check the reception signal quality to ensure good reception.
5. Household appliance such as fridge, lighting, dimmers may pose Electro-magnetic interference (EMI),
while Radio Frequency Interference (RFI) from devices operating in the same frequency range may
cause signal intermittent. Choose a location at least 1-2 meter (3-5 feet) away from these interference
sources to ensure best reception.

3.1.4 ADJUST THE SOLAR PANEL
The tilting angle of solar panel can be adjusted vertically from 0 into 15°, 30°, 45° and 60° positions
depending on the area you are living in. For optimal power output year-round, please set the tilt angle that
is closest to your latitude.
E.g.
LOCATION (LATITUDE, LONGITUDE) SOLAR PANEL TILT ANGLE
Berlin (52.5484, 13.3736) 60°
Chicago (42.1146, -88.0464) 45°
Houston (29.7711, -95.3552) 30°
Bangkok (14.2752, 100.5684) 15°
Sydney (-33.5738, 151.3053)* 30°
*Sensors installed in Southern Hemisphere must have their solar panels facing North.
Step 1: Loosen the screw lightly until the gears on the
opposite side separated from lock position.
Step 2: Push the screw inward until the gears on the
opposite side separated from lock position
Step 3: Adjust the vertical angle of the solar panel (0°, 15°,
30°, 45°, 60°) according to the latitude of your location.

1b. Apply 2 rubber pads on the mounting clamp.
2. Apply 2 rubber pads on the inner sides
of the mounting base and clamp of the
sensor-array, and loosely fasten them
together.
3. Place the sensor-array over the mounting pole and
align it to North direction before fastening the screws.
NOTE:
- Any metal object can attract lightning strikes, including your sensor-array mounting pole. Never install
sensor-array in stormy days.

12
- If you want to install a sensor-array on a house or building, consult a licensed electrical engineer to
ensure proper grounding. Direct lightning impact on a metal pole can damage or destroy your home.
- Installing the sensor at high location may result in personal injury or death. Perform as many initial
inspections and operations as possible on the ground and in buildings or houses. Only install the sensor-
array on clear, dry days.
- Ensure the sensor-array installation place is stable and no vibration.
3.1.7 DIRECTION ALIGNMENT
Install the wireless 7-in-1 sensor in an open location
with no obstructions above and around the sensor for
accurate rain and wind measurement.

3.1.8 POINTING THE WIRELESS 7-IN-1 SENSOR TO SOUTH
The outdoor 7-in-1 sensor is calibrated to point to North for the maximum accuracy. However, for the user's
convenience (e.g. users in the Southern hemisphere), it is possible to use the sensor with the wind vane
pointing to South.
1. Install the 7-in-1 wireless sensor with its wind meter end pointing to South. (Please refer to
Section 3.1.7 for mounting details)
2. Select "S' in set hemisphere step (Please refer to Section 4.4 for setup details)

distance and barriers between the sensor transmitter and the console.
1. Electromagnetic interference (EMI) – these may be generated by machinery, appliances,
lighting, dimmers and computers, etc. So please keep your console 1 or 2 meters away
from these items.
2. Radio-frequency interference (RFI) – if you have other devices operating on 868 / 915 / 917
MHz, you might experience communication intermittent. Please re-located your transmitter
or console to avoid signal intermittent problem.
3. Distance. Path loss occurs naturally with distance. This device is rated to 150m (450 feet)
by line of sight (in interference free environment and without barriers). However, typically
you will get 30m (100 feet) maximum in real life installation, which includes passing through
barriers.
4. Barriers. Radio signal are blocked by metal barriers such as aluminum cladding. Please
align the sensor array and console to get them in clear line of sight through window if you
have metal cladding.
The table below show a typical level of reduction in signal strength each time the signal passed through
these building materials
MATERIALS SIGNAL STRENGTH REDUCTION
Glass (untreated) 10 ~ 20%
Wood 10 ~ 30%
Plasterboard / drywall 20 ~ 40%
Brick 30 ~ 50%
Foil insulation 60 ~ 70%
Concrete wall 80 ~ 90%
Aluminum siding 100%
Metal wall 100%
Remarks: RF signal reduction for reference
3.4 POWER UP THE CONSOLE
3.4.1 INSTALL BACKUP BATTERY AND POWER UP
1. Backup battery provides power to the console to retain clock time and date, max/min
records and calibration value.
Step 1 Step 2 Step 3
Remove the console
battery door with coin Insert a new CR2032 button cell battery Replace the battery door.
NOTE:
- The backup battery can backup: Time & Date and Max/Min records.
- The built-in memory can backup: calibration value and connection settings.

15
- Please always remove the backup battery if the device is not going to be used for a while. Please keep in
mind that even when the device is not in use, certain settings, such as the clock, calibration and records
in its memory, will still drain the backup battery.
2. Plug in the power adapter to power up the console.
3.4.2 SETUP THE CONSOLE
1. Once the console is power up, all the segments of the LCD will be shown.
2. The console will automatically enter AP mode and sensor synchronization mode
automatically.
NOTE:
If no display appears when power up the console. You can press [ RESET ] key by using a pointed object. If
this process still not work, you can remove the backup battery and unplug the adaptor then re-power up the
console again.
3.5 SYNCHRONIZING WIRELESS 7-IN-1 SENSOR

strength indicator and weather reading will appear on your console display.
3.6 DATA CLEARING
During installation of the wireless 7-in-1 sensor, the sensors were likely to be triggered, resulting in
erroneous rainfall and wind measurements. After the installation, user may clear out all the erroneous data
from the display console. Simply press the [ RESET ] key once to re-start the console.
