This document describes a proposed automated blood bank system using Raspberry Pi and Android applications. The system aims to connect blood donors and patients needing transfusions. Donors can register their blood type and details using an Android app. When a patient needs blood, they enter their request into the app which matches it to donor information stored on a Raspberry Pi database. The system then sends an SMS notification to a matched donor using a GSM modem connected to the Raspberry Pi. The system is intended to streamline the process of fulfilling emergency blood requests.
