    Hi. I have a $600 weather station that logs and connects to my pc. I am using also an aftermarket software Weather Display with whom i have access to talk to the developer and add features etc if needed.

    MY station doesnt have a solar uv meter on it and i would like to add it.
    i have seen this on facebook
    http://www.ebay.com.au/itm/UVA-UVB-...119075?hash=item2a73203d23:g:qoEAAOSw8w1YBzk9

    and wondered how i would go about connecting this to my pc so then the developer can use the date and add to the software.

    Thanks for any assistance.

    Look for an I2C interface card for the PC.

    I would be more likely to feed it to an Arduino, and let that transmit the data to the PC using the USB serial port emulator.

    would something like this be what you mean and to eliminate Arduino?

    Here's the datasheet. https://www.vishay.com/docs/84304/veml6075.pdf

    I didn;t look at everything, but thiss https://www.adafruit.com/product/2264 could be a piece of the puzzle

    Issue that I immediately see is logic level translation 5 V /3.3. I2C bus Speed (didn't look), USB powered (didn't look)

    Both USB and I2C have bus limitations in terms of length.

    Here's SOME information on I2C: http://www.esacademy.com/en/library...c-bus/frequently-asked-questions/i2c-faq.html

    You will likely have to encapsulate it and any glass used could alter the response. Quartz might work. See: https://www.janis.com/products/AccessoriesandAncillaryEquipment/WindowTransmissionCurves.aspx

    Not sure exactly what you trying to do. You might be better off using a solar cell of the same material and an appropriate filter. Where I did Solar cell measuremnst, we happened to have a bunch of 1 sqcm non-AR (anti-reflection coated) cells that we could use for calibration. A National laboratory measured our standards and we created more of them. When I test a-Si cells, I needed a cell with a filter.

    The sun;s spectra is known as AM 1.5 Global.

    So, this is info without trying to digest everything. It's areas that need to be looked at.
