Description

The Skywatch BL-500 is a specialised, ultra-portable atmospheric sensor array designed to turn any smartphone into a high-accuracy meteorological station via Bluetooth connectivity. Engineered for rapid field deployment, it features a ruggedized IP67-rated housing that protects a high-sensitivity multidirectional propeller and internal solid-state sensors for Air Temperature, Relative Humidity, Barometric Pressure, and UV Index. Optimised for handheld or tripod-mounted use, the Skywatch BL-500 requires no complex wiring or external power, utilising a rechargeable battery and a dedicated app for real-time data visualization and GPS-tagged logging. For professional users, it can be seamlessly integrated with a ball-head clamp for fixed-position monitoring, providing a modular and pocket-sized alternative to traditional distributed station infrastructures.
