I did the green banana test on my diy UV-C Sterilizer (see https://www.greenequitybuilders.org/pdfs/UV_Box.pdf) and the results were decidedly underwhelming. Since I got no response from the UV-C bulb manufacturer to my inquiry for UV-C irradiance information, I am understandably nervous as to whether there is sufficient germicidal effect from my sterilizer. I, therefore, need a way to measure UV-C irradiance around the 254nm wavelength, and I imagine there are other makers who might also need to measure the irradiance of their own UV-C projects.
I did a little research and I found the 1918 ANALOG UV SENSOR BREAKOUT Board (see https://www.adafruit.com/product/1918) and that looked promising except that it has very poor sensitivity in the germicidal UVC wavelength range.
But then I saw that the GUVC-S10GD photodiode has a spectral range of 220nm - 280nm, which is ideal!
(See https://www.digikey.com/product-detail/en/genicom-co-ltd/GUVC-S10GD/2096-GUVC-S10GDCT-ND/10475469)
Do you think the GUVA-S12SD photodiode on the 1918 ANALOG UV SENSOR BREAKOUT Board could be de-soldered and replaced with the GUVC-S10GD photodiode (or the GUVC-S40GD, or something similar) to get a better UVC sensor breakout board for germicidal UVC projects?
I don’t have enough electronics experience yet to understand what sorts of modifications to breakout boards are possible, so I’m reaching out to other engineers & makers who have more expertise. It would be great to open source a diy project for building a UV-C photometer around an Arduino and some inexpensive off-the-shelf components.
