Introduction
Thank you for selecting Wi-fi weather station with 5-in-1 professional sensor. This system gathers and
automatically uploads accurate and detailed weather data to Weather Underground and Weathercloud
website - the famous weather service which allows weather observers to upload their local weather data with
automated personal weather stations (PWS) - at which you can access and upload your weather data freely.
This product offers professional weather observers or serious weather enthusiasts robust performance with
a wide range of options and sensors. Youwill get your own local forecast, high/lows, totals and averages for
virtually all weather variables without using a PC.
This weather station which transmits in / outdoor temperature, humidity, wind and rain data, which can add
to a sensor array of maximum 7 units, transmits your temperature & humidity to the console. Both sensors
are fully assembled and calibrated for your easy installation. They send data at a low power radio frequency
to the console from up to 150m away (line of sight).
In the console, a high-speed processor is embedded to analyze the received weather data and these real-
time data can be published to Wunderground.com and weathercloud.net through your home Wi-fi router.
The console can also synchronize with internet time server to keep the time and weather data time stamp
of high precision. The LCD display shows informative weather readings with advanced features, such as
high/low alert alarm, different weather index, and MAX/MIN records. With calibration and moon phase
feature, this system is truly a remarkably personal yet professional weather station for your own
backyard.
Note:
This instruction manual contains useful information on the proper use and care of this product.
Please read this manual through to fully understand and enjoy its features, and keep it handy

Dew point
The dew point is the temperature below which the water vapor in air at constant
barometric pressure condenses into liquid water at the same rate at which it evaporates.
The condensed water is called dew when it forms on a solid surface.

EN 19
The dew point temperature is determined by the temperature & humidity data fromwireless
IN-1 sensor .
Weather forecast
The built-in barometer can notice atmosphere pressure changes. Based on the data collected,
it can predict the weather conditions in the forthcoming 12~24 hours within a 30~50km (19~31
miles) radius.
Sunny
Partly cloudy
Cloudy
Rainy
Rainy / Stormy
Snowy
Note:
The accuracy of a general pressure-based weather forecast is about 70% to75%.
The weather forecast is reflecting the weather situation for next 12~24 hours, it may not
necessarily reflect the current situation.
The SNOWY weather forecast is not based on the atmospheric pressure, but based on the

Barometric pressure
The atmospheric pressure is the pressure at any location of
the earth caused by the weight of the column of air above it.
One atmospheric pressure refers to the average pressure and
gradually decreases as altitude increases. Meteorologists use
barometers to measure atmospheric pressure. Since variation in
atmospheric pressure greatly affected by weather, it is possible to
forecast the weather by measuring the changes in pressure.
To set the barometer unit
In normal mode, press [ BARO UNIT ] key to change the barometer unit in this sequence:
hPa→ inHg → mmHg
To view the absolute / relative barometric reading
In normal mode, press and hold [ BARO ] key to switch between ABSOLUTE / RELATIVE
barometric reading.
To set relative atmospheric pressure value
Go to “Advanced Setting in Web Interface” on page 11.
E.g. If your local REL reading is 1010 hPa, and the difference to the reading of the unit, say 1013
hPa, then enter “-3” into the box.
Rainfall
The RAINFALL section shows the rainfall and rain rate information
To set the rainfall unit
1 . Press and hold [ RAIN ] key for 2 seconds to enter unit setting mode.
2 . Press [ Ʌ ] or [ V ] key to toggle the rainfall unit between mm and in.
3 . Press [ RAIN ] key to confirm and exit the setting.
