    Done ;-)

    little confusion with my Pyranometer project...
    Yes I've no correlation except the good behavior on blue sky <> the colder result with a conversion close to 9000/10000m and cloudy days provided some results close to the reality...
    I'll share my first results asap.

    Thanks for your comments and advices... that sound really good, and could be the source of my third Design ;-)

    Just to clarify (I should add several pix of the head of the sensor) I don't use a light sensor.
    We operate by absorption of the full Visible light sprectum trough a black body (two little copper squares) in contact with a diode (the hot diode) The absorption create an increasing temperature which create a proportional current leak from the diode... We compare it with the 'cold diode' and the gap define the power level.
    The system is really simple and the correlation was really good so easily.

    But now for sure, a pelletier component could provide accuracy on low radiation level and the silica dome reduce the filtration. Great!
