What does a UV sensor measures or detects???
anyone have any ideas??

this might seem like a trite answer, apologies in advance.

Ultra Violet Light?

Ultra Violence :lol:

Maybe you should be more specific and give us some more data.
eg where is the uv sensor or is it like a handheld device?

It measures or detects UV.

Ultra violet... light spectrum... in whatever scenario there is some... could be a VCR sensor, or for sunbathing/tanning/etc, or whatever, you failed to give a context.

its for measuring stains in bed linen 😳

or fingerprints =)

Ok, I had a look at your other post. Mondoman suggested that you were probably a student and this was a project set for you. I'm guessing that he was right as you are still asking. For anyone else this was Serendipity's other post;

Lets start with the basics then, UV is Ultra Violet light and is part of the electromagnetic spectrum along with visible light (the light we can see). UV light is given off by the sun which is what you want to detect with your outdoor UV monitor, unless you have another reason for monitoring UV light for sports. Anyway just search UV in wikipedia and although it will take a while to read that way you might actually understand it.

Yep, that's all good advice. I'll toss out some more stuff. For example, you might want to study up a little on optical filter media. If you want to make a UV monitor, you'll want to be specific and just measure the wavelength range for UV. You can use a bandpass filter to let UV through and block everything else or you can try to find a detector that is only sensitive to UV. All the above is coming from the electronic measurement angle. You don't have to use an electronic device to do this. You can use materials that chage color upon exposure to UV then calibrate the color change as a function of UV dose. So maybe you need to narrow the scope of your project and define what's required to successfully solve it.
