I ordered NO2 ( 968-047) and O3 ( 968-046) sensing voltage modules.
As you can see, the sensitivity calibration code is missing, which is normally present next to that barcode.
I’m pretty sure I need that calibration constant for my arduino code. Is there anywhere else I can find it?
Welcome to the TechForum!
I’m a bit curious, have you tried scanning the QR code on the sensor? If so, does it take you anywhere specific?
I’m not very familiar with this product line, and am checking with my colleagues to locate an answer to your question, so hopefully we can get an answer to you shortly!
I have scanned both the QR codes, but it just show that nothing can be found. Thank you.
Thank you for your information.
