GMX500 Compact Weather Station


The GMX500 Compact Weather Station is designed for easy installation, use, and maintenance. In addition to providing measurement parameters, these products also derive other parameters, output as a single string, and can be used with a range of communication protocols.


MaxiMet weather stations benefit from the same technology as the Gill scientific product line, ensuring measurement accuracy, low maintenance, and continuous status reporting.


The MaxiMet series includes a range of sensor configurations, allowing customers to choose the model that best suits their needs.


Typical Applications

- Control systems, including smart buildings, agriculture, and industry

- Solar power plants

- Highways and railways

- Ports

- Transportation and safety reporting systems

- Low-power/solar deployments and IoT applications



Key Features

- Five measurement parameters: wind speed and direction, temperature, humidity, pressure, optional heating, optional GPS functionality

- Multiple additional derived parameters based on combined measurements (such as gusts, average wind speed, and dew point)

- High-quality, high-precision, solid-state sensors

- 2-axis compass

- Optional integrated GPS functionality for providing location, GPS timestamps, and true wind calculations when the platform is moving

- Optional low-power heating



Advantages

- High-quality measurements achieved through careful sensor selection and extensive design testing and validation

- Easy setup and integration using comprehensive software to select desired reporting and export parameters and measurement units

- Easy installation and long service life due to compact, rugged design and low-maintenance sensor selection

- Suitable for use with battery or solar systems in low-power mode
