Product Description

The UV Light Sensor measures ambient ultraviolet intensity in the 200  to 370 nanometer range, within the solar ultraviolet UVA, UVB, and UVC light spectrum. The sensor has a built-in amplifier with adjustable levels. The UV Light Sensor may be used outdoors in a variety of applications including datalogging and closed-loop control, such as for activating watering or greenhouse vents.

The single analog output may be directly connected to the Propeller Activity Board 4-channel A/D converter or easily interfaced with the MCP3002 A/D with a FLiP Multicore Microcontroller.


  • Partial UVA (370-340nm), UVB (340-315 nm), partial UVC (315-200 nm) light measurement with a simple analog output
  • 200–370 nm response spectrum for a wide range of natural solar light levels
  • Adjustable amplification
  • 2 to 5 volt analog output is easy to read by many controllers or A/D converters
  • 9 inch (22 cm) 3-pin female-female extension cable included

Application Ideas:

  • Ultraviolet intensity exposure measurement and datalogging
  • Automatic shade system trigger
  • Control systems for gardening, plant growth, watering systems commonly used in greenhouses

Key Specifications:

  • Response spectrum: 200–370 nm

    Is there a exact relationship between wave length an analog output?

    Stephanie Lindsay

    Best to refer to the response curve in the GUVA-S12SD datasheet; I’ve posted it under the Downloads & Resources tab of this page for you.

    Alan McRae

    If the GUVA-S12SD on this breakout board was de-soldered and replaced with the GUVC-S10GD photodiode would it still work, except that the photodiode output curve would have to be re-calibrated?

    If it would work, how hard is it to de-solder/re-solder an SMD photodiode?


    The description mentions adjustable gain – can you provide documentation on this please

    Stephanie Lindsay

    I have made inquiries with the manufacturer; I have also added a link to their product wiki page under Downloads and Resources if you wish to explore further in the mean time.
