This SparkFun Qwiic Spectral UV Sensor features the AS7331 UV sensor from ams OSRAM©. It measures UV radiation on three channels: UVA (320-400nm), UVB (280-320nm), and UVC (200-280nm) with high sensitivity and accuracy. The three channels on the AS7331 each have individual photodiodes with built-in interference filters. The sensor has four operating modes: Single Measurement (CMD), Continuous Measurement (CONT), SYNchronized Start (SYNS), and SYNchronized Start & End (SYND), with an automatic power-down sequence between measurements for low current consumption in all three modes.

Any chance to get a grip of the step file for handheld enclosure? Looks nice for a quick hookup!

[@lucalanzi9345]

Can you please explain how to change the addresses of the sensors

[@TiczAdam]

So is it capeable to measure a the sun also? So I can decide do I need to apply any protection.

[@robreynolds6546]

Yes, absolutely! I got solid reading outdoors.

[@TemporalRecall]

Is there a difference between the two modules aside from the PCB layout / size?

[@robreynolds6546]

No difference other than the layout. If you check out the schematics on the product pages, they're the same circuit.

@@robreynolds6546 Thanks 😀

[@baddestmofoalive]

Why won’t you give any Pi-5 pre-order updates?

[@yeet1337]

What are the actual output units? I doubt it's some absolute units, so is it just basically some arbitrary ones to get the ratios only? Also, I'm pretty sure that are laser safety glasses, so, uh.. why? 😂😅

[@robreynolds6546]

It's using standard uv measurement units of uW/cm2. (Also, the glasses? UV Safety Glasses TK-3-SG. Similar in color to laser safety glasses for certain types of lasers.)

@@robreynolds6546 Is it just me or do the numbers in the video not make sense logically? 66uW/cm2 is like 0.66W/m2 which is a uv index of over 25. I bought one of these and simply being under the sun read values of over 1000 which would be deadly exposure in UV index. I think it may be more like uW/m2 because that's the only one I can see being reasonable.
