Hi All,

I want to measure the measure the solar irradiance up to 1500W/m2.

I already found this discussion, but the link in answer looks like dead.

Is it possible to get information about the reply?

Thansk in advance.

Hi Lionel,

From the discussion you linked to it looks like some light attenuation would be required to bring the light level down into the range of the sensor while also increasing the gain of the sensor. Is there a specific part of the linked discussion that you have more questions about?

Best,

Alex

Hi Alex,

Thanks for your answer. We will put a light filter, but what it is the minimum Rext I can put ?

Hi Lionel,

I do not believe there is a minimum, but you'll need to check how low of a gain you are okay with. I do not have the device with me to test on at this time, however, so cannot confirm this.

Best,

Alex
