Description

Sky temperature seems to be an abstract value, but this is quite a good indicator of current conditions. Even under dark sky far away from light pollution, when high clouds are present, then sky background meter may show very low values. But high clouds will affect astrophotography significantly. The sky temperature sensor will detect high clouds as well as any other clouds, fog, haze, and similar obstacles in the air.

Sky temperature is the measured value, but the informative value is the difference between the sky temperature and ambient temperature. If there is no difference it indicates 100% clouds or dense fog. If the sky temperature is 20-25 degrees lower than ambient, it means very few obstacles in the air, so the transparency should be good.

This sensor can be also used for contactless temperature measurements of any object (like house walls, radiators, floor, etc).

Technical data:

  • ambient temperature range:  -40C … +50C
  • sky temperature range:  -70C … +380C
  • field of view: 30 degrees
