The Role of IOT for Monitoring the Wastage of Vaccines Due to Poor Cold Chain Management

COVID-19 is a deadly infectious disease caused by the recently discovered coronavirus. It is a severe acute respiratory syndrome which is spreading at an enormous rate that needs early control. IoT technologies can be successfully used in the management of spread of virus and maintenance of cold-chain. This review article discusses the role of IoT (Internet of things) in management of cold- chain during covid-19 pandemic. The use of a data centric vaccine cold chain monitoring system is mentioned which can monitor the temperature, and humidity and can track the location of vaccine carriers and in case of emergency sends notification to the health care supervisor, along with IoT technologies RFID, Wi-Fi, Bluetooth, and GPS embedded devices are in use. IoT based scannable devices are also in use for the monitoring of temperature and location tracking. In addition, this article proposes an ESP8266 Wi-Fi based module, which maintains the temperature and humidity of the vaccine carrier box; any changes in temperature from its optimum range sends a single cooling tool embedded in it which then manages to maintain the temperature. This proposed system will be helpful in the maintenance of the cold chain followed by the reduction of vaccine wastage.
