    Connected Compact Station BWS500


    Air quality is always connected to the weather. Conversely, weather also affects air quality.

    Because of this, air quality measurements are much more valuable if they are accompanied by real-time data about wind speed and direction, temperature, humidity, and other factors that directly affect pollution and its travel.

    Vaisala BWS500 is an elegantly simple system with integrated weather and air quality sensors, network connectivity, and data storage — forming a scalable platform for weather and environmental observations, as more stations can be easily added later, and stations can be relocated as needed.

    Wireless and secure



    BWS500 is a complete package, taking care of the air quality measurements as well as the data storage and transfer via 4G LTE wireless communication.

    Vaisala Beacon Edge Gateway EGW501 provides a secure data transfer between the sensors and the BWS Cloud Companion cloud software. The integrated SIM card and cellular data plan make the station ready for use as soon as it is installed.

    Gain confidence from BWS500 industry-leading data integrity and security measures, which protect your weather network and data from modern threats.

    Powerful data management



    The optional cloud-based Vaisala BWS Cloud Companion software collects and visualizes measurement data from the station. Once you have an account in BWS Cloud Companion, you can easily share the data to third-party services and systems through an open API.

    Key measurements



    Connected Compact Station BWS500 uses the industry-leading WXT536 Weather Transmitter, along with AQT530 Air Quality Transmitter to produce full-spectrum air quality and weather intelligence. This provides a much more intelligent understanding of air quality, its fluctuations, and the drivers affecting it.
