1  Using Arduino / Sensors / Re: Electrochemical sensors e2v-memebrapor on: November 19, 2013, 01:59:20 pm
I have to realize a circuit for this sensor ... from e2v ...
Someone else has ever use this kind of sensors? what kind of circuit  have you use?

I see some discussion about using very similar sensors from the same company (e2v) at
http://electronics.stackexchange.com/questions/91157/shunt-calculate-dissipation-resistor
.
That discussion has a few links to circuit schematics -- will any of those schematics work for you?

Is this sensitive enough to see any stars in the sky (other than our sun) in the daytime?
How did you think that could be done, what is your idea, and in what purpose would you like to use that?
...
If you want to get the temperature of the star, you need a bit different technic for that.

I wonder if this could be done by pointing the thermal camera at the sky, without any other changes to the hardware or software.

I think it would be cool to have a time-lapse movie showing the stars apparently revolving around the celestial pole for a full (24 hour) cycle.
(I don't need to get the temperature of the star for that, right?)

I've been told that the vast majority of all stars in our galaxy are red dwarfs. Most of the energy a red dwarf star emits is in the infrared.

Cool!
