Design and implementation of automatic autoclave temperature and pressure data recording system

Abstract

Abstract Sterilization data history is needed to maintain and examine an autoclave performance to minimize the risk of sterilization failure. This study aimed to develop a sterilization data recording system for an autoclave with external data storage using an SD card. The TFT LCD is used as the user interface to make it easier for users to monitor temperature and pressure during the sterilization process. The MAX 31865 temperature sensor and the MPX 5700 AP pressure sensor are used to monitor the temperature and pressure in real-time during the sterilization process. The entire sterilization process of the developed system is controlled using The ATMega 2560 microcontroller. Three testings have been carried out to determine the designed temperature, and the pressure data recording system has been a success, Temperature data recording, Pressure data recording, and Process data recording. Based on the conducting test results, the designed recording system gives an excellent performance to record the temperature, pressure level, and data sterilization process with a success rate of 100%.
