Description

technical field [0001] The invention relates to the technical field of detection, in particular, it is a humidity detection device designed based on IP65 waterproof level. Background technique [0002] Humidity is a physical quantity that expresses the degree of dryness of the atmosphere. The less water vapor there is in a given volume of air at a given temperature, the drier the air; the more water vapor, the wetter the air. The degree of dryness and humidity of the air is called "humidity". In this sense, it is often expressed by physical quantities such as absolute humidity, relative humidity, comparative humidity, mixing ratio, saturation difference, and dew point; if it expresses the weight of water vapor in wet steam as a percentage of the total weight (volume) of steam, it is called is the humidity of the steam. The humidity that the human body feels comfortable is: the relative humidity is lower than 70%. [0003] There are three basic forms of humidity, namely w...
