[0003] Due to the limitation of structure and space, the existing temperature and humidity measurement method directly arranges the temperature and humidity sensor on the PCB board, and the PCB board will heat up after being powered on, and the temperature rise caused by the heating of the PCB will cause the temperature measured by the temperature and humidity sensor to be higher than the real ambient temperature , the humidity is also inaccurate, which affects the accuracy of the temperature and humidity sensor measurement data

Embodiment Construction
[0029] Next, the technical solutions in the embodiments of the present invention will be described in contemplation in the embodiments of the present invention, and clearly, as described herein is merely, not all of the embodiments of the present invention. Based on the embodiments of the present invention, those of ordinary skill in the art will belong to the scope of the present invention without all other embodiments obtained without creative labor.
[0030] It should be noted that all directional indications (such as above, lower, left, right, front, and then ...) are intended to be interpreted between the components under a particular attitude (as shown in the drawings). The relative positional relationship, the movement condition, etc., if the specific posture changes, the directional indication is also correspondingly changed.
[0031] It will also be noted that when the element is referred to as "fixed to" or "set to" on another element, it can be directly in the other ele...

The invention discloses a method for calibrating humidity, which is characterized in that it comprises the following steps of obtaining saturated humidity corresponding to different temperatures under a predetermined atmospheric pressure, as well as measuring temperature and ambient temperature; correcting the measured temperature to obtain a corrected temperature; obtaining the measured temperature and the corrected temperature The corresponding saturated humidity; according to the saturated humidity at the measured temperature, correct the saturated humidity at the temperature to correct the measured humidity. The humidity calibration method provided by the present invention uses the principle that the saturated humidity ratio at the corresponding temperature is equal to the unsaturated humidity ratio at the corresponding temperature to calibrate the measured humidity. The temperature difference affects the inaccuracy of the measured ambient humidity; further, the present invention also provides a humidity calibration module using the calibration method and a dehumidifier using the humidity calibration module, which can sense the environment more accurately Humidity, for more precise automatic control.
Description
Technical field [0001] The present invention relates to the field of measurement data calibration, and more particularly to a humidity calibration method, and a calibration module and a dehumidifier using the method. Background technique [0002] Through experiment, since humidity changes with temperature change, when the temperature of the moisture sensor is higher than the ambient temperature, then the humidity result measured by the humidity sensor is a temperature rise, and is not the actual environmental humidity. [0003] Due to structural and space limit, the existing temperature and humidity measurement method directly puts the temperature and humidity sensor on the PCB board, while the PCB plate will heat, the PCB heating generates warmth, which causes the temperature of the temperature and humidity sensor to be high than the actual ambient temperature. , Humidity is also inaccurate, affecting the accuracy of the temperature and humidity sensor measurement data.
