Abstract

The invention discloses a humidity detecting system based on full-wave rectification design. A transformer T, a rectifying circuit, a filtering circuit and a humidity detecting and processing circuit are arranged; the primary end of the transformer T is connected with a 220V alternating-current power source, the secondary end of the transformer T is connected with the alternating-current input end of the rectifying circuit, the direct-current output end of the rectifying circuit is connected with the filtering circuit, and the filtering circuit is connected with the humidity detecting and processing circuit. A switching circuit, a voltage stabilizing tube Z1, a capacitor C1, a time-based oscillating circuit and a sensor circuit are arranged in the humidity detecting and processing circuit, and the first end of the direct-current output end of the rectifying circuit is connected with a negative pole of the voltage stabilizing tube Z1 and the time-based oscillating circuit through the switching circuit. After the alternating-current power source is subjected to rectification processing through a full-wave finishing technology, ripple voltage in rectified direct-current voltage is removed through the filtering circuit, needed work voltage is provided for the humidity detecting and processing circuit, and humidity information in the environment can be detected.

Description

technical field [0001] The invention relates to the technical field of detection, specifically, a humidity detection system based on a full-wave rectification design. 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 water ...
