Wireless UV Sensor Node – uvLink IoT
uvLink IoT – Wireless UV Sensor Node for Real-Time Solar Radiation and UV Index Monitoring Networks
The uvLink IoT from SGLUX GmbH is an advanced wireless UV sensor node designed for continuous, real-time monitoring of solar ultraviolet radiation and UV Index (UVI) levels.
It integrates a TOCON-series UV sensor with wireless data transmission, a micro-controller, and an autonomous power supply, creating a compact, stand-alone IoT unit.
Equipped with LoRaWAN, Wi-Fi, or Bluetooth Low Energy connectivity, uvLink IoT enables long-range data transfer to cloud dashboards or local networks without cabling.
Its solar-powered design, low power electronics, and NIST/PTB-traceable calibration guarantee accurate, maintenance-free field operation.
The rugged IP67 weatherproof housing ensures reliable performance in harsh outdoor environments such as meteorological stations, smart-city networks, agriculture, and UV-safety systems.
Compact, precise, and fully autonomous, uvLink IoT transforms professional UV Index measurement into a scalable smart-network solution.
Understanding Wireless UV Sensor Node - uvLink IoT
The uvLink IoT measures erythemally effective UV irradiance and transmits corresponding UV Index (UVI) data wirelessly to servers or cloud platforms.
It combines a calibrated TOCON UVI sensor, onboard signal conditioning, and a wireless communication module inside a single, self-powered unit.
The device is completely autonomous — powered by solar energy and backed by long-life rechargeable batteries — allowing years of operation without maintenance.
With traceable calibration, cosine-corrected optics, and cloud-ready protocols, uvLink IoT delivers professional-grade UV Index monitoring for environmental, scientific, and safety applications.
