Introduction
The Lark Weather Station Pro is an upgraded version of the standard model(https://www.dfrobot.com/product-2785.html), featuring a base expansion module that adds GNSS positioning, WiFi connectivity, battery monitoring, and wireless data transmission. It records temperature, humidity, air pressure, wind speed, and direction—either offline to CSV files or online via SIoT (V1/V2) servers. Setup is simple: configure via USB drive, deploy indoors or outdoors, and monitor data locally or in the cloud. With clear LED status indicators and support for both PC and Unihiker M10 as MQTT brokers, it’s perfect for STEM education and real-world environmental sensing projects.
