ABSTRACT
It is impossible to manufacture the blood, as it can be given by the donors. Blood bank retrieval information can be given through the android studio application, but there is not much work on the integrated environment like IoT sensor connected with android studio application development. This paper provides the IoT healthcare sensors connected to the android studio mobile application development blood donors and blood receivers. The mobile application is most useful in an emergency during the COVID-19 pandemic. This observational study gives the web-based application development and also android-studio mobile application development for blood bank information retrieval system. The results are carried out in a real-time environment and updated features of the blood bank mobile application.
