AMBIENT COMPENSATED SOLAR SENSOR
First Claim
Patent Images
1. An ambient compensated solar sensor comprising a support, a pair of matched thermal sensors mounted on said support in fixed widely spaced thermally insulated relation to substantially prevent heat transfer between said thermal sensors, and a shield surrounding and protecting from solar radiation one of the matched thermal sensors, the other of said matched thermal sensors being unshielded.
