Seeed Studio S-ZW-01 | Industrial UV Radiation Sensor (RS485 Modbus RTU)

The Seeed Studio S-ZW-01 is an industrial ultraviolet (UV) radiation meter engineered to provide critical sunlight intelligence for environmental and agricultural applications. Utilizing a high-sensitivity photoelectric detector and specialized optical filters, this sensor converts incident UV radiation into a proportional electrical signal, delivering accurate intensity readings in W/m². Its cosine-corrected design ensures measurement fidelity even at wide incidence angles, making it a reliable component for permanent outdoor installation in harsh climates.

Advanced Meteorological Sensing

Optimized UV Bandwidth Tuned to the 290–390nm range, capturing the most significant UV radiation for biological and material impact studies. Modbus RTU Standard Equipped with an RS485 interface for easy integration with data loggers, PLCs, or LoRaWAN Modbus DTUs. Rugged Outdoor Enclosure UV-resistant casing with IP66 protection ensures consistent performance in rain, dust, and high-heat environments. Compact Integration Small form factor with standardized wiring allows for easy mounting on weather station masts and cross-arms.

Professional Use Cases

• Smart Agriculture: Monitor UV exposure to predict crop health, optimize fertilization, and study the impact of radiation on pest behavior. • Meteorological Research: Capture high-resolution UV intensity data for atmospheric studies and UV index forecasting. • Materials Testing: Track UV aging and degradation of outdoor materials in industrial testing sites.

Technical Integration

The S-ZW-01 operates on a wide 7V to 24V DC power supply and communicates via RS485 Modbus RTU, making it fully compatible with the SenseCap ecosystem and other professional industrial networks. For wireless deployment, it can be bridged to LoRaWAN® using a Modbus DTU. For assistance with payload decoding or meteorological station architecture, contact the ShopIoT engineering team.
