Abstract
A ventilating fan, includes a humidity sensor box, provided with an air inlet in a bottom surface facing an suction opening and an air outlet in a top surface opposite to the bottom surface; a humidity sensor located inside the humidity sensor box and adapted to detect the humidity of the air passing through the humidity sensor box; and a humidity sensor circuit board located inside the humidity sensor box, disposed perpendicular to the bottom surface and adapted to control the humidity sensor. The air may flow at a high speed in the humidity sensor box, and it is easy for the water vapor to be taken out of the humidity sensor box without being accumulated inside the humidity sensor box, thereby suppressing the influence of the water vapor or the water droplet on the humidity sensor and enabling the humidity sensor to accurately detect the indoor humidity.
