Network Nodes (IoT) – UV Index Transmitter
IoT-Enabled UV Index Transmitter for Smart Environmental Monitoring and Networked Ultraviolet Radiation Measurement Systems
The UV Index Transmitter (IoT Network Node) is an intelligent, connected sensor designed for continuous monitoring and wireless transmission of UV Index and irradiance data. Built around a calibrated SiC photodiode sensor with traceable NIST/PTB calibration, it accurately detects UVA and UVB radiation (250–400 nm) and converts measurements into a standardised UV Index (0–11+) value.
Equipped with LoRaWAN / Wi-Fi / RS485 communication interfaces, this IoT node integrates seamlessly into environmental monitoring stations, smart cities, agricultural systems, and weather networks.
The transmitter continuously reports real-time UV intensity, temperature, and status data to cloud dashboards or local SCADA systems.
Its IP65-rated weatherproof housing, low power consumption, and auto-calibrated electronics make it ideal for long-term outdoor operation.
The UV Index Transmitter offers a reliable, scalable, and traceably calibrated solution for automated UV radiation monitoring in research, meteorology, and industrial safety applications.
Understanding Network Nodes (IoT) - UV Index Transmitter
The UV Index Transmitter (IoT Node) functions as a smart environmental sensor that continuously measures UV radiation and wirelessly communicates the data for analysis and control.
It uses a factory-calibrated SiC UV photodiode to detect solar or artificial UV radiation and calculates the UV Index following WMO/WHO standards.
Real-time readings are transmitted through network protocols such as LoRaWAN, Wi-Fi, or Modbus RTU, enabling remote access via cloud dashboards or local gateways.
With low maintenance requirements, long operational life, and traceable calibration, it supports large-scale deployment in smart monitoring networks, agricultural automation, and climate research systems.
