I.Product Overview
The TRM-GPS4 Micro Weather Station is the third-generation portable weather station independently developed by our company. It features compact size, light weight and rugged durability. Compared with previous-generation products, the TRM-GPS4 boasts higher accuracy, more powerful functions and more flexible operation modes. When paired with a data acquisition terminal, it can either be carried around for real-time data viewing and on-site monitoring, or permanently installed outdoors for long-term fixed monitoring. It is set to become a flagship product for handheld weather stations.
This micro weather station is capable of monitoring environmental temperature and humidity, ultrasonic wind direction and speed, optical rainfall, air pressure, solar radiation, illumination intensity and other meteorological elements. Meanwhile, it supports the expansion of gas and particulate matter detection including CO、NO₂、 SO₂、 O₃、TVOC and PM2.5 Equipped with Bluetooth communication and cloud platform data management functions, it is compatible with both AC and DC power supply and features low power consumption. It is widely used in diverse fields such as environmental protection, meteorology, transportation, water conservancy, agriculture, and landscaping.
II.Product Features
1. The TRM-GPS4 Micro Weather Station is the most compact meteorological monitoring instrument, boasting the combined advantages of small size, full functionality and high accuracy.
2. It adopts a combined mode of micro weather station + data acquisition terminal. The micro weather station transmits data to the data acquisition terminal via Bluetooth. While monitoring meteorological data, it can also realize multiple functions such as GPS positioning and electronic compass through mobile phones.
3. The instrument’s display and operation are based on the world’s most popular full-lamination IPS retina screen, which supports color temperature adjustment. The full-lamination technology significantly improves screen light transmittance and ensures better contrast even under strong light. With IPS technology, it offers a 178° viewing angle, enabling clear visibility from any perspective without direct alignment with the screen. It features clear and intuitive display as well as excellent animation effects, achieving fully intelligent man-machine interaction.
4. The micro weather station has a full-metal casing and reaches IP66 protection rating, featuring small size, light weight and rugged durability. It supports both AC and DC power supply with low power consumption. The output signal is customizable, allowing the station to adapt to various monitoring environments.

6. Unmatched Functional Power Among Peer Micro Meteorological InstrumentsIts measurable parameters include: wind speed, wind direction, air pressure, ambient temperature, ambient humidity, solar radiation, dew point, altitude, longitude and latitude, GPS satellite positioning, electronic compass, photo/video recording, mobile phone call function, and GPRS wireless data network. It also allows for expansion of additional monitoring parameters including CO, NO₂, SO₂, O₃, TVOC, PM2.5, and PM10.
7. System Software FunctionsThe professional network-version software is capable of monitoring measurement data from multiple weather stations within the system. The monitoring coverage extends wherever the stations are deployed, capturing real-time monitoring time, location, and current environmental data. Its performance fully complies with the requirements of the national "Automatic Weather Station Standards and Specifications". Featuring a user-friendly interface with graphical data display, the software is compatible with Windows 2000 and above operating systems. It can connect to a printer for automatic printing and storage of data, with data saved in standard EXCEL format. The system can generate meteorological data charts that are exportable for use with other software applications.
8. Integrating the Advantages of Multiple Micro Weather StationsThe TRM-GPS4 Micro Weather Station breaks away from the traditional mechanical appearance. Its all-metal casing offers far greater robustness and durability compared with plastic enclosures. Equipped with an ultrasonic wind speed and direction sensor, it delivers higher measurement accuracy. It is truly a micro meteorological instrument with the smallest footprint and the most powerful functions on the market.
9. Versatile Monitoring Modes with Solar Power OptionThe device supports handheld mobile monitoring, vehicle-mounted monitoring, and fixed monitoring when mounted on a portable monitoring bracket. It also offers an optional solar power supply to meet the needs of on-site applications.
