Hi all,
I am certainly keen on building some sort of 1-Wire UV Sensor from scratch. Am considering purchasing a Oregon UVR 138 as a first step with the possibly converting that to a 1-wire if someone could give me a Circuit Diagram of one.
The other thing I was considering was using (as Mike above) a 1-wire battery monitor DS2438Z and either using the VSense+ input or the VAD depending on the output of UV sensor and the Opamp circuit. Anyone got any preliminary designs that would consider sharing?
I did find the following UV sensor and circuits which is a starting point. http://www.kyosemi.co.jp/product/data/en/KPDU34PS1.html
As I have only basic Electronics knowledge, would anyone consider collaborating with me on this? The only issue I see then would be calibrating it accurately.
Colin, I would be keen to talk to you on the phone to see what you have.
Thanks.
Cheers
