Quote:You can connect it directly to an Arduino analog input, but with a so low voltage output from the sensor, if you don't amplify it, you will get a very poor resolution (this is what the Solar / UV interface does).
I know...at this moment it's connected to a Siemens !LOGO PLC wich is monitoring/controlling my pool.
Quote:I liked the sensor enclosure... nice idea. It seems that someone has started to industrially produce solar radiation sensors based on the method we discuss here for years!
It's not a new product. The first version , the SOZ-01 was released in 1989. Bought the SOZ-03 six years ago directly from the German engineer.
Calibrated and with certificates.
Quote:Interesting these specs from a solar radiation sensor based on PV cells:
*Accuracy of monthly sums compared to a W.M.O. class 1 Pyranometer (e.g. CMP 11) according to ISO 9060: better ±5
*Very small drift of <0.3 / year (experience since 1989)
Have you ever opened the box of your sensor? What is inside?
Yes, connected the cables but can't remenber. I can take some pics next days.
