The signal level from the photodiode\nis very small, in the nano-amp level an opamp is thrown to amplify the signal\nto a more manageable voltage level. This sensor is much simpler than the\nSi1145 breakout, it does only one thing and gives an analog voltage output\ninstead of requiring a complicated I2C setup procedure. This makes it better\nfor simple projects. It also features a \"real\" UV sensor instead of a\ncalibrated light sensor. To use, power the sensor and op amp by connecting V+\nto 2.7-5.5VDC and GND to the power earthing. Then read the analog signal from\nthe OUT pin. The output voltage is: Vo = 4.3 diode current-in-uA. So if the\nphoto current is 1uA (9mW\/cm2), the output voltage is 4.3V. You can also\nconvert the voltage to UV index by dividing the output voltage by 0.1V. So if\nthe output voltage is 0.5V, the UV index is about 5. Please note that UV LEDs\n400nm are outside the range of this sensor. So if you try to test this sensor,\ndo not use it. A UV tanning lamp or \"lizard lamp\" works much better.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003eAdd light sensor to your Arduino or Raspberry Pi project\u003c\/li\u003e\n \u003cli\u003eRequires soldering of pin jaws\u003c\/li\u003e\n \u003cli\u003eEasy to use\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-09-02T10:45:28+10:00","created_at":"2026-09-02T00:17:19+10:00","vendor":"Adafruit","type":"Optical Sensors","tags":["industrial_DE_Aug2026"],"price":13100,"price_min":13100,"price_max":13100,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":44375089545396,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"de-B00NAY2EUC","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit GUVA-S12SD Analog UV Light Sensor Breakout","public_title":null,"options":["Default Title"],"price":13100,"weight":20,"compare_at_price":null,"inventory_management":"shopify","barcode":"701980281778","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/auspowers.com\/cdn\/shop\/files\/de-B00NAY2EUC.jpg?v=1788272242","\/\/auspowers.com\/cdn\/shop\/files\/41hJA-V4bfL.jpg?v=1788272242","\/\/auspowers.com\/cdn\/shop\/files\/51CnwbtzdqL.jpg?v=1788272242"],"featured_image":"\/\/auspowers.com\/cdn\/shop\/files\/de-B00NAY2EUC.jpg?v=1788272242","options":["Title"],"media":[{"alt":null,"id":33273711296692,"position":1,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/de-B00NAY2EUC.jpg?v=1788272242"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/de-B00NAY2EUC.jpg?v=1788272242","width":500},{"alt":null,"id":33273711329460,"position":2,"preview_image":{"aspect_ratio":1.0,"height":500,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/41hJA-V4bfL.jpg?v=1788272242"},"aspect_ratio":1.0,"height":500,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/41hJA-V4bfL.jpg?v=1788272242","width":500},{"alt":null,"id":33273711362228,"position":3,"preview_image":{"aspect_ratio":1.0,"height":500,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51CnwbtzdqL.jpg?v=1788272242"},"aspect_ratio":1.0,"height":500,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51CnwbtzdqL.jpg?v=1788272242","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit GUVA-S12SD Analog UV Light Sensor Breakout\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eExpand your light sensor spectrum with the Adafruit analogue UV sensor module.\nIt uses a UV photodiode that can detect the 240-370nm light range (which\ncovers UVB and most of the UVA spectrum).
