PRECAUTIONS
Thank you for selecting Professional Weather Station with integrated 5in1 multi-sensor.
The wireless 5in1 sensor contains a selfemptying rain collector for measuring rainfall, anemometer, wind vane, temperature, and humidity sensors. It is fully assembled and calibrated for easy installation. It sends data by a low-power radio frequency to the Display Main Unit up to 150m away (line of sight). The display Main Unit displays all the weather data received from the 5in1 sensor outside. It remembers the data for a time range for you to monitor and analyze the weather status for the past 24 hours. It has advanced features such as the HI /LO Alert alarm which will alert the user when the set high or low weather criteria are met. The barometric pressure records are computed to give users forthcoming weather forecasts and stormy warnings. Day and date stamps are also provided to the corresponding maximum and minimum records for each weather detail.
The system also analyzes the records for your convenient viewing, such as the display of rainfall in terms of rain rate, daily, weekly and monthly records, whereas windspeed in different levels, and expressed in Beaufort Scale. Different useful readings such as Windchill, Heat Index, Dewpoint, and Comfort level are also provided.
With Radiocontrolled / Atomic clock feature builtin, the system is truly a remarkable personal 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 for future use.

Your wireless 5IN1 sensor measures windspeed, winddirection, rainfall, temperature, and humidity for you.
It’s assembled and calibrated for your easy installation.
INSTALL BATTERIES
Unscrew the battery door at bottom of the unit and insert the batteries according to the +/ polarity indicated. Screw the battery door compartment on tightly.
Note:
ASSEMBLY THE STAND AND POLE Step 1
Insert the top side of the pole to the square hole of the weather sensor.
Note:
Ensure the pole and sensor’s indicator align.
Step 2
Place the nut in the hexagon hole on the sensor, then insert the screw in the other side and tighten it with the screwdriver.
Step 3
Insert the other side of the pole to the square hole of the plastic stand.
Note:
Ensure the pole and stand’s indicator align.
Step 4
Place the nut in the hexagon hole of the stand, then insert the screw in the other side and then tighten it by the screwdriver.
Install the wireless 5IN1 sensor in an open location with no obstructions above and around the sensor for accurate rain and wind measurement. Install the sensor with the smaller end facing the North to properly orient the wind direction vane.
Secure the mounting stand and bracket (included) to a post or pole, and allow a minimum 1.5m off the ground
Mounting guidelines:
Stand and batteries installation
The unit is designed for desktop or wall mount for easy viewing.
Note:
Pairing of wireless 5in1 sensor with Display Main Unit
After the insertion of batteries, the Display Main Unit will automatically search and connect the wireless 5in1 sensor (antenna blinking).
Once the connection is successful, antenna marks and readings for outdoor temperature, humidity, wind speed, wind direction, and rainfall will appear on the display.
Changing batteries and manual pairing of sensor
Whenever you changed the batteries of the wireless 5in1 sensor, pairing must be done manually.
Note:
Radiocontrolled / atomic clock function
When the unit receives RC signal, a synctime symbol “” will appear on the LCD, and synchronizes daily.
Note:

To set the alarm time
The device contains sensitive pressure sensor builtin with sophisticated and proven software that predicts the weather for the next 12 ~ 24 hours within a 30 to 50km (1931 miles) radius.
Note:
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 is greatly affected by weather, it is possible to forecast the weather by measuring the changes in pressure.
To select the display mode:
Press and hold [BARO] button for 2 seconds to toggle between:
• ABSOLUTE the absolute atmospheric pressure of your location
• RELATIVE the relative atmospheric pressure based on the sea level
To set relative atmospheric pressure value:
Note:
To select the measurement unit for the barometer:
To select the rainfall display mode:

To view Wind Chill:
Press the [INDEX] button repeatedly until WINDCHILL displays.
Note: The wind chill factor is based on the combined effects of temperature and wind speed. The wind chill displayed is calculated solely from temperature and humidity measured from the 5in1 sensor.
To view Heat Index:
Press the [INDEX] button repeatedly until HEAT INDEX displays.
Heat Index range | Warning | Explanation |
27°C to 32°C (80°F to 90°F) | Caution | Possibility of heat exhaustion |
33°C to 40°C (91°F to 105°F) | Extreme Caution | Possibility of heat dehydration |
41°C to 54°C (106°F to 129°F) | Danger | Heat exhaustion likely |
≥55°C (≥130°F) | Extreme Danger | Strong risk of dehydration/sunstroke |
Note: Heat index is only calculated when the temperature is 27°C/80°F or above, and based solely on the temperature and humidity measured from the 5in1 sensor.
To view DewPoint (Indoor)
Press the [INDEX] button repeatedly until DEWPOINT displays.
Note: 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.
The dewpoint temperature is calculated from the indoor temperature and humidity measured at the Main Unit.
The Display main unit automatically record and display data of past 24 hours on the hour.
To check all the history data in the past 24 hours, press the [HISTORY] button.
E.g. Current time 7:25 am, Mach 28
Press [HISTORY] button repeatedly to view past readings at 7:00am, 6:00am, 5:00am, …, 5:00am (Mar 27), 6:00am (Mar 27), 7:00am (Mar 27)
The LCD will display the past indoor and outdoor temperature & humidity, value of air pressure, wind chill, wind speed, rainfall, and their time and date.
HI/LO alerts are used to alert you of certain weather conditions. Once activated, the alarm will turn on and amber LED starts flashing when a certain criterion is met. The following are areas and types of alert provided:
Area | Type of Alert available |
Indoor temperature | HI and LO alert |
Indoor humidity | HI and LO alert |
Outdoor temperature | H I and LO alert |
Outdoor humidity | HI and LO alert |
Rainfall | HI alert |
Wind speed | H I alert |
Note: Daily rainfall since midnight.
To set the HI / LO alert
To enable/disable the HI / LO alert
Note:
The 5in1 sensor is capable of transmitting data wirelessly over an approximate operating 150m range (line of sight).
Occasionally, due to intermittent physical obstructions or another environment in the reference, the signal may be weakened or lost.
In the case that the sensor signal is lost completely, you will need to relocate the Display main unit or the wireless 5in1 sensor.
Comfort Indication
The comfort indication is a pictorial indication based on indoor air temperature and humidity in an attempt to determine comfort level.
Note:
1. Comfort indication can vary under the same temperature, depending on the humidity.
2. There is no comfort Indication when temperature is below 0°C (32°F) or over 60°C (140°F).
During the installation of the wireless 5in1 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
Main Unit, without needing to reset the clock and reestablish pairing. Simply press and hold the [HISTORY] button for 10 seconds. This will clear out any data recorded before.
The outdoor 5in1 sensor is calibrated to be pointing to North by default. However, in some cases, users may wish to install the product with the arrow pointing towards the South, especially for people living in the Southern hemisphere (e.g. Australia, New Zealand).
In the Northern hemisphere, the moon waxes (the part of the moon we see that glows after the New M o o n ) from the right. Hence the sunlit area of the moon moves from right to left in the Northern Hemisphere, while in the Southern Hemisphere, it moves from left to right.
Below are the 2 tables which illustrate how the moon will appear on the main unit. Northern hemisphere:
