Technical Field

The invention relates to the technical field of humidity detection, in particular to a humidity detection device.

Background

Conventional humidity sensing sensors include resistive or capacitive humidity sensing sensors, for example, the humidity sensitive element is the simplest humidity sensing sensor, and the humidity sensitive element mainly includes resistive and capacitive humidity sensitive elements. The resistance-type humidity-sensitive element is characterized by that a layer of film made of humidity-sensitive material is covered on the substrate, when the water vapour in the air is adsorbed on the humidity-sensitive material, the resistivity and resistance value of the resistance-type humidity-sensitive element are changed, and the humidity measurement can be implemented by utilizing said characteristic. The capacitive humidity sensor is generally made of a polymer film material, and the polymer material commonly used includes polystyrene, polyimide, acetate butyrate, and the like. When the environmental humidity changes, the dielectric constant of the capacitance type humidity sensitive element changes, so that the capacitance of the capacitance type humidity sensitive element also changes, the capacitance change quantity of the capacitance type humidity sensitive element is in direct proportion to the relative humidity, and the humidity is further detected.
