Design and Implementation of a Constant Humidity Control System

Abstract

In this paper, a constant humidity control system based on PID algorithm is designed. The humidity signal is detected by capacitance sensor, connected to the MXT9030 for processing, and the capacitance value is converted to voltage value and sent to the MCU. The constant humidity control system adopts PID control algorithm, which has the characteristics of convenient implementation and stable control. The system is very suitable for modern families that require a comfortable environment and has wide application prospects.
