Design and Implementation of Multiple Vaccine Monitor System Using IoT and Android Application

Abstract

—The need for safe distribution of Covid-19 vaccines is indispensable for all parties to minimize the risk of distribution. Vaccine monitoring systems has advantage that officers or supervisors can continuously monitor multiple device such as the temperature, shock and cold box position during the distribution process. When the cold box temperature is outside the specified temperature range, the system will give warnings in the form of notifications through the android smartphone application and can also be accessed via the website so that vaccine carrier can condition the cold box by increasing or decreasing ice packs so that the quality of the vaccine can be maintained. Equipped with a location tracking system using GPS, it can provide information on the presence of vaccines to supervisors in real time. This system consists of a DS18B20 temperature sensor, a shock sensor using MPU6050 and a GPS sensor using UBLOX NEO-6M GPS module. The sensors are connected to a microcontroller ATMega 2560 chip in a single printed board along with a battery power supply. The notification feature is very helpful for vaccine carrier and supervisors when an abnormal event occurs in the cold box so that it can facilitate the decision-making process.
