As an air temperature and humidity sensor is used a special sensor of my own production, which contains the SHT25chip including special housing (IP67). The sensor is placed in a shade in a radiation shield with a fan (controlled by a computer according to the current level of solar radiation). As the radiation shield is used a small radiation shield from a common weatherstation.
