基于单片机和PID算法的温度智能控制系统设计OACSTPCD

An intelligent temperature control system is designed to improve the intelligent level of temperature control.In the system,STC89C52 microcontroller is used as the controller,and PID algorithm is used to control temperature,which has functions such as voice broadcasting and mobile remote control.DS18B20 temperature sensor is used to collect environmental temperature,the LCD12864 display circuit is designed to display real-time current temperature,upper and lower limits of temperature,and temperature status.The WT588D voice reminder circuit is designed to emit a voice reminder when the measured temperature is below or above the lower limit.The button circuit is designed to set the upper and lower temperature limits.The Bluetooth communication circuit is designed to communicate with mobile APP and achieve remote control,and the PID algorithm is used to output control variables and control solid-state relays to drive heating or cooling devices,achieving temperature control.The hardware and software design of the temperature control system are designed,and the physical object is maken,operational testing is conducted by the experiments.The experimental results show that the designed temperature control system can realize the expected effect,can effectively achieve temperature control,and is easy to operate,low-cost,and had strong application value.
