On my roof i have a calibrated solar radiation sensor giving a voltage of 90...110 mV @ 1000 W/m²

This is the sensor i have.

Is it useable with the TX board?

Hi Zappie,

Yes but you will need to make sure this is compatible with the input voltage used by the arduino. In the main thread of this topic it is explained in details how to proceed: in a nutshell, to benefit from the highest precision, we need to have an input signal as large as the arduino input maximum voltage. In the case of this article this is 1.1V. So you will need to build the interface published by Werk and adjust R1 and R2 to obtain the gain that will maximise the sensor output corresponding to the maximum irradiation (that may be higher than 1000W/m2 by the way).
In your case it seems that a gain of about 10 would be required. Read the thread first.
