Temperature, light, and humidity are significant factors for the quality control of cold storage pharmaceutical products. Especially, temperature is a major factor in the quality reduction of products. The increase of temperature interacts with the quality of pharmaceutical products. Also, the pharmacist always monitors the temperature of the refrigerator via a data logger. However, a conventional data logger requires payment for an SMS notification. Moreover, a commercial refrigerator is equipped with a single temperature sensor. Consequently, the temperature monitoring system can only report the top temperature of the refrigerator. However, the arrangement of pharmaceutical products inside the refrigerator obstructs the direction of cold temperature air flow. Thus, the pharmacist cannot know the bottom temperature inside the refrigerator. If the temperature increases at the bottom of the refrigerator, then the quality of the pharmaceutical products is reduced. As a result, a conventional temperature monitoring system cannot observe the real-time temperature. The arrival of the internet of things (IoT) and smart devices has inspired the development of a conventional pharmaceutical data logger inside refrigerators. Thus, this work presents the enhancement of the reporting system of a cold storage pharmaceutical refrigerator using IoT devices. The results indicate that the pharmacist can monitor the real-time behavior of a vaccine refrigerator. Moreover, the proposed system reduces the cost of a conventional data logger. The proposed system notifies the pharmacist when the temperature exceeds or is lower than the critical point. The proposed system confirms that the pharmacist can make a fast response. Moreover, the proposed system eliminates the limitation of a conventional pharmaceutical temperature monitoring system.
