Abstract

The invention discloses a household appliance humidity detecting method and a household appliance humidity detecting device. A first square wave signal output by a first signal output port of a control chip and a second square wave signal output by a second signal output port of the control chip are output to a humidity detecting module, the humidity detecting module generates a sampling voltage signal according to the first square wave signal and the second square wave signal, the control chip determines the humidity value corresponding to the sampling voltage signal generated by the humidity detecting module according to the mapping relation of the preset voltage and the humidity, so as to acquire the humidity value of current environment, and therefore, the household appliance humidity detecting cost is reduced.

Description

technical field [0001] The invention relates to the technical field of humidity detection, in particular to a humidity detection method and device for household appliances. Background technique [0002] In order to be able to monitor air humidity, many household appliances have a humidity detection function. At present, the air humidity is generally obtained by installing a humidity detection module on a household appliance, and the humidity detection module has its own detection chip or detection circuit, and outputs approximately linear temperature and voltage corresponding parameters through the humidity detection module. The disadvantage of the prior art is that the cost of the humidity detection module installed in the household appliance for detecting humidity is relatively high. Contents of the invention [0003] The main purpose of the present invention is to provide a humidity detection method and device for household appliances, aiming at solving the technical p...
