Temperature and humidity
As an air temperature and humidity sensor is used a special sensor of my own production, which contains the SHT25
chip 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.

Location:2m above ground in an active rad.shield
Accuracy:typ. ± 0,2°C, humidity ±1,8%
Resolution:0,01°C, humidity 0,04%RH
