Take control of the data! MQTT (Message Queuing Telemetry Transport) is a lightweight and efficient messaging protocol that makes it easy to stream live scientific data directly to your desktop or mobile device.
Why just watch when you can interact? Our MQTT stream gives you real-time access to the exact spectral data being measured outdoors by our spectrometer at our Tampa headquarters.
Getting started is quick and requires no complex setup or coding experience — just use a standard MQTT client to subscribe and start receiving data. Of course, if you enjoy coding or have development experience, MQTT client libraries are available for various programming languages, giving you full flexibility to build custom tools, scripts, or integrations.
