UV detection module

The Grove UV Sensor detects incident ultraviolet radiation intensity across a 240 to 370 nanometre spectral range. It outputs an analog signal proportional to UV levels so a microcontroller can calculate the UV Index for sun-exposure guidance. The module operates from 3.0 to 5.1 volts and draws only 0.31 milliamps.

Compact Grove form factor

The board measures 20 by 20 by 15 millimetres and weighs 8 grams. A unified Grove socket provides plug-and-play connectivity with a supplied cable, eliminating soldering and allowing quick integration with many 3.3 or 5 volt microcontrollers and single-board computers. The sensor maintains specified performance from minus 30 to 85 degrees Celsius.

Spectral range 240 to 370 nanometres

This single specification defines the ultraviolet bandwidth the sensor can measure. It covers UV-B and most UV-A wavelengths but does not extend into visible light or UV-C regions. Buyers needing detection outside this window or requiring calibrated absolute irradiance in watts per square metre should select a different instrument.

Questions about this item

What voltage range does the Grove GUVA-S12D UV Sensor accept?

The sensor operates from 3.0 V to 5.1 V and draws 0.31 mA, so it works directly with 3.3 V or 5 V microcontrollers.

How large is the board and what does it weigh?

The module measures 20 mm by 20 mm by 15 mm and weighs 8 g, fitting tight enclosures without extra mounting hardware.

How do I connect the sensor and what mistake should I avoid?

Plug the included Grove cable into the unified socket; the only common error is reversing the cable, so align the notch before pressing it in.
