Gravity: GUVA-S12SD Analog UV Light Sensor (200-370nm, UVA, UVB, UVC)

The Gravity GUVA-S12SD Analog UV Light Sensor measures ultraviolet radiation across the 200 to 370 nm spectrum, covering UVA, UVB, and UVC light. It is an ideal tool for students, makers, and environmental researchers building solar monitoring systems and weather stations.

Broad UV spectrum detection

Powered by the GUVA-S12SD chip, this sensor accurately detects ultraviolet radiation in sunlight between 200nm and 370nm.

Linear analog output

The module delivers a fast response with a linear analog voltage output. Readings can be converted directly into the World Health Organization UV index grading scale.

Compact and easy installation

Its small footprint and standard Gravity analog interface make it simple to integrate into enclosures, robotics setups, and portable monitors.

Versatile monitoring applications

This sensor is well suited for UV index tracking, plant growth environmental control, UV-A lamp monitoring, and custom maker projects.

Included in the kit

Each pack includes one GUVA-S12SD analog UV sensor and one Gravity analog connection cable.
