PRO 800 is the most complete instrument of the range. The device measures 7 environmental indicators:
- air temperature,
- relative humidity,
- atmospheric pressure,
- wind direction and speed,
- precipitation intensity,
- solar radiation power,
- UV index.
Air temperature
The temperature in the weather station is measured by an NTC thermistor (NTC – Negative Temperature Coefficient). The NTC-thermoresistor is a semiconductor which decreases in resistance as the temperature increases. The sensor works in the range from -50 °C to +60 °C.
Air humidity
The device measures relative humidity of the air with the help of a capacitive sensing element in the range from 1 to 100%.
Atmospheric pressure
Absolute atmospheric pressure is calculated from absolute zero (absolute vacuum) and is measured using sensors with microelectromechanical components (MEMS).
Relative pressure is calculated relative to the earth’s atmosphere depending on the altitude of the weather station site above sea level.
Wind direction and wind speed
Wind direction and wind speed are measured using 4 ultrasonic sensors (ultrasonic anemometer). They cyclically record the airflow readings in the 4 directions of light. The device then calculates the result with an accuracy of ±3%.
Precipitation intensity
An optical rain gauge calculates the intensity of rainfall over a given period. It can also calculate the total amount of precipitation for a day.
Solar radiation power, UV index
The instrument is equipped with a pyranometer, a meteorological sensor for measuring radiation. It is installed in the dome of the weather station and can record the UV-index (ultraviolet radiation).
Additional sensors
The PRO 800 weather station can also be extended with an additional radar precipitation sensor. It records the speed of falling raindrops (or snowflakes) and calculates the amount of precipitation by comparing the size of a drop (snowflake) and its speed of fall.
Weather station housing
The construction of the weather station is compact and robust due to the absence of obsolete mechanical elements.
The plastic, ventilated housing is designed to protect the sensors from environmental influences and to ensure trouble-free operation of the weather station. The warranty period is 1 year from the date of commissioning.
Software and communication interface
To manage the weather station, Jcom-iot programmers have developed a software called “IMETEOLABS PRO Configurator”. It allows you to view the data collected by the device in the form of tables and graphs.
PRO 800 weather station works in 2 encodings: ASCII format and MODBUS protocol.
The RS485 (twisted pair) interface is used for connection with other devices.
Working principle
Smart weather station PRO 800 is connected to one of three devices:
- controller of data collection and transmission units (wireless data transmission via NB-IoT/LoRaWAN/3G);
- interface converter (data transmission via Ethernet cable);
- computer (using RS-485/USB adapter).
These devices are used to transfer data from the weather station to the software “IMETEOLABS PRO Configurator”.
The software is available as an application for one PC or as an IoT platform on a separate server. The second option is more flexible: you can connect from any PC via a web browser and store data from other smart devices in a single system.

John –
Outstanding and comprehensive weather station! It measures everything you could need – from wind and rain to solar radiation. The ultrasonic anemometer is a game-changer for accuracy. The ability to add a radar sensor is a great feature.
