碩士 === 國立勤益科技大學 === 電子工程系 === 106 === In this thesis, the STM32F407 microcontroller is used as the core of PID control system. The system mainly collects temperature through the K-type thermocouple temperature sensor. The STM32F407 is displayed the digital temperature value on the TFT LCD display to let the user know the current temperature. The oven temperature measured using a K-type thermocouple is displayed in digital form, and the PID is used to adjust the temperature. The K-type thermocouple has a working range of (-40 ° C to + 600 ° C). In this study, PID temperature control is used to regulate temperature, and solid state relays are used to control proportional ON-OFF type heater power. The use of solid state relays allows devices that control larger currents with lower current signals. The PID of parameter control can be adjusted through MODBUS RTU mode, mainly to achieve temperature stability and baking time and fan switch in the electric oven.
