Pyranometer AmplifierThe described amplifier is a high sophisticated part of a solar irradiation measurement and logging project.

The most important unit of a solar radiation measurement system is a good , trusted and calibrated radiation sensor. Such a sensor is very expensive and hard to get just for hobby projects. On the WEB there are some publications which deal with different sensor solutions. I checked some of these, but finally I decided to buy a commercial ISO9060 Seconardy Standard Pyranometer ( it hit a big dent in my hobby finances! ). But it was worth it, it works perfect.
However , a sensor is just "half of the trip". A Pyranometer delivers about 4 ... 14 uV/W/m2 . The output voltage must be converted to a range which can easily be detected and processed. This requires an amplifier which is able to cover the given resolution and the given voltage range (0..15mV) in a wide temperature range, with less noise, offset and drift.
Maybe this helps others who are looking for similar solutions, even for non solar projects.(Click to to get it! )
