Title:
METHOD AND APPARATUS FOR JUDGMENT OF AIR-QUALITY LEVEL
Document Type and Number:
Japanese Patent JP3026895
Kind Code:
B2
Abstract:
PURPOSE: To correct a temperature value and a humidity value to an output from an air-quality detection means and to easily and accurately judge an air-quality level even when the temperature value and the humidity value fluctuate.
CONSTITUTION: This apparatus is provided with an air-quality detection means 11 which detects the state of an air quality, a temperature and humidity detection means 12 which detects a temperature value and a humidity value, and a storage means (a reference-value output means) 13 provided with temperature information which is established between various kinds of temperature values and humidity values and an output value from the air-quality detection means in an air quality as a reference. In addition, the apparatus is provided with an operation means 14 wherein, on the basis of the temperature value and the humidity value which have been detected, relational information is referred to, the threshold value of an absolute judgment standard for a predetermined air-quality level is corrected to obtain the judged threshold value of the air-quality level in the detection of an air quality, the output of the air-quality detection means 11 in the detection of the air quality is compared with the judged threshold value of the air-quality level in the detection of the air quality to judge the air-quality level.
