基于单片机的温度控制系统设计

AbstractDesign of temperature control system Based on SCMAbstractIn today's developing society,the industry and life are increasing.The previous designsystem has been unable to meet the needs of today's society,so the design of the more requiredtemperature control system is the inevitable trend.The design of the temperature control systemcan make the temperature adjustment more simple and flexible,and save the operation cost.Thispaper will use the STC89C51 single-chip microcomputer to design a temperature control system,using the temperature sensor for data collection,the LCD display shows the current temperature.When the temperature of the device exceeds or below the preset temperature interval,the alarmissues a warning and the relay begins to control the corresponding device for temperature controloperation to control the temperature within the preset interval.Finally,the design is adjusted andimproved through simulation.This system can be used as a water heater temperature controlsystem,a greenhouse temperature control system,etc.The system has great flexibility and iseasy to adjust.Key words:single chip microcomputer;relay;temperature sensor;digital tube
