摘要
以STM32控制器为控制核心,进行温湿度控制器的设计,给出了部分主控电路和RS232收发电路。通过温湿度传感器检测温度和相对湿度,根据数字增量式PID控制算法控制环境温湿度接近给定值。通过系统软、硬件联机调试,该控制器实现了高精度的温湿度控制与无线传输,且工作可靠。
Having STM32 controller cored,a temperature and humidity controller was designed,including main control circuit and RS232 send-receive circuit.In which,the temperature and humidity sensors can de-tect both temperature and relative humidity and keep them close the given value through an incremental PID control algorithm.The on-line debugging system’s hardware and software shows that this controller can control both temperature and humidity accurately and can achieve wireless transmission along with a reliability.
