Mobile air-temperature measurement imposes specific requirements in terms of measurement quality and easy of use.
Measurement quality means:
-very fast response in order to catch the sharp temperature variations that typically occurs in mobility. The standard car thermometer, due to its slowness (imposed by the need shielding the solar radiation) is completely unable to detect such variations.
-solar radiation error minimization without reducing the measurement time, which means that ordinary shielding structures cannot be deployed, given the relevant ventilation reduction that they determine.
Also, lightness, compactness and easy of installation are key features for a device that aims at wide diffusion among professionals and amateurs.
The MeteoTracker multi-sensor addresses all these issues by a dual-sensor approach (patent pending), that does not require any particular shielding (thus permitting huge sensing elements ventilation) since the solar radiation is corrected by means of a differential method consisting in a calibrated diffence in radiation exposure of the 2 sensing elements.
This way, the typical speed-temperature dependency experienced in mobility with a standard temperature sensor (the slower the higher is temperture reading and viceversa) is removed as well.
