Abstract: One embodiment provides a pyranometer, including: a dome; a thermopile-based sensor comprising a receiving surface; a diffusor configured to diffuse radiation external to the pyranometer and passing through the dome, toward the receiving surface of thermopile-based sensor; and at least one optical filter arranged in an optical path of the radiation in front of the receiving surface of the thermopile-based sensor so as to modify the spectral composition of the radiation measured by the thermopile-based sensor. Other aspects are described and claimed.
