An autoclave is a sterilization device that uses high-pressure steam to eliminate microorganisms. However, in conventional systems, pressure regulation is still performed manually, which can cause inconsistencies and reduce sterilization effectiveness. This study developed an automatic pressure control system utilizing a digital pressure sensor managed by an Arduino Uno microcontroller and equipped with an ESP8266 module for Internet of Things (IoT)-based real-time monitoring. The system also integrates a MAX6675 temperature sensor, a solenoid valve as a pressure actuator, and an LCD as a local display. Testing was conducted at three pressure levels—10, 15, and 25 psi—for 15 minutes each. The results demonstrated that the system maintained pressure stability within ±0.5 psi and successfully transmitted temperature and pressure data to a cloud dashboard in real time. Overall, the system effectively enhances efficiency, accuracy, and safety in the sterilization process, showing strong potential for medical and laboratory applications.
