The Turkish coffee maker highlights traditional brewing methods by combining ultra-fine coffee grounds, sugar, and water in a pot and brewing them slowly at low temperatures. This process enhances the flavor and allows the grounds to naturally settle at the bottom of the cup, which requires precise water level monitoring and exact temperature control.
Geehy’s Turkish coffee maker solution, powered by the industrial-grade basic APM32F003 MCU, optimizes performance, communication, integration, and power efficiency to meet critical requirements for temperature regulation, user interaction, and safety. This user-centered solution provides an optimal experience for Turkish coffee enthusiasts.
Overview of the APM32F003 Turkish Coffee Maker Solution
The APM32F003 MCU serves as the main control unit, ensuring precise heating control, interactive functionality, and safety protection to enhance the user experience.
Heating Control: When the coffee cup is placed in the machine, a mechanical structure precisely positions the temperature sensor probe within the cup. Integrated with the MCU’s ADC input, the sensor continuously monitors and maintains water temperature to ensure a consistent, low-temperature brewing process. This feature also supports automated shutdown and accommodates standard boiling and tea preparation functions.
User Interaction: The APM32F003 MCU manages up to four mechanical buttons through an ADC pin voltage divider, enabling short and long press actions. It also controls LED indicators and a buzzer, guiding users throughout the brewing process.
Safety Protection: The MCU uses timer capture to detect cup placement and monitor water levels with an ultrasonic sensor, automatically suspending heating to prevent overheating or dry burning.
