Automatic control system based on self-shaping signal filtering circuit and used for humidifier

Abstract

The invention discloses an automatic control system based on a self-shaping signal filtering circuit and used for a humidifier. The automatic control system is characterized by mainly comprising a central processing unit, the signal filtering circuit, a preset value storage unit, a control circuit, a displayer, a filtering and noise-reducing circuit, a power source, a humidity sensor and the humidifier. The signal filtering circuit, the preset value storage unit, the control circuit, the displayer and the filtering and noise-reducing circuit are connected to the central processing unit, the power source is connected to the filtering and noise-reducing circuit, the humidity sensor is connected to the signal filtering circuit, and the humidifier is connected to the control circuit. The automatic control system is simple in structure and low in cost, can automatically control the humidifier to humidify the indoor space when the indoor humidity is excessively low and can automatically control the humidifier to stop humidifying the indoor space when the indoor humidity is excessively high, and therefore the indoor humidity can be maintained within the range suitable for promoting the human health. The automatic control system is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to an automatic control system, in particular to an automatic control system for a humidifier based on a self-tuning signal filter circuit. Background technique [0002] Humidifiers are gradually favored by people because they can humidify indoor air, especially in winter when the weather is dry, and humidifiers have become an indispensable household appliance for many people. When using a humidifier, the humidifier will continuously spray water mist into the air, making the indoor air more humid. However, the living environment of people is not that the higher the air humidity, the better. The humidifiers currently in use cannot know the humidity of the indoor air and can only humidify the air blindly, which brings great inconvenience to users. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the currently used humidifier cannot know the humidity of the indoor air and can o...
