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

Abstract

The invention discloses an automatic control system used for a humidifier and based on a self-shaping voltage stabilization type signal filtering circuit. The automatic control system is characterized by being mainly composed of a central processing unit, a signal filtering circuit, a preset value storage unit, a control circuit, a display, a filtering and noise reducing circuit, a voltage stabilization circuit connected with the filtering and noise reducing circuit, a power source connected with the voltage stabilization circuit, a humidity sensor connected with the signal filtering circuit, and the humidifier connected with the control circuit, wherein the signal filtering circuit, the preset value storage unit, the control circuit, the display and the filtering and noise reducing circuit are connected with the central processing unit. The automatic control system is simple in structure and low in cost, the humidifier can be automatically controlled for humidification when the indoor humidity is too low and can be automatically stopped humidifying continuously when the indoor humidity is too high, and therefore it can be ensured that the indoor humidity is kept in a proper range beneficial to the health of the human body; and the automatic control system is suitable for application and popularization.

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-shaping voltage stabilizing 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...
