摘要： The sensor has an outer member 10 formed with an upwardly directed hole 12 having an open upper end 14. An inner member in the form of a tube 16 is provided having a lower portion 18 positioned in the hole 12 and an upper portion 19 which projects above the outer member 10. Solar radiation applied to the upper portion 19 of the tube 16 creates a chimney effect which causes air to flow upwardly inside the tube 16 and downwardly from the open upper end 14 through a space 22 between the inner and outer members 10, 16. Sensing devices 24, 26 for sensing temperature and humidity are arranged within the outer member 10 and in the air flow path.
