| Abstract | Blood donation facilities are essential for providing blood in times of need; however, problems,
including unavailable donors, inefficient manual processes, and poor inventory control, make
management difficult. For the purpose of improving accessibility, dependability, and efficiency
in blood bank activities, this study suggests an Internet of Things-based blood stock control
system. Real-time blood stock monitoring is made possible by the system’s integration of RFID
technology, cloud-based data transfer, and Internet of Things sensors (temperature, relative
humidity, and infrared). In order to verify appropriate storage, the first module consists of sensors
placed in blood storage racks to monitor stock levels and environmental conditions. Monitoring
from a distance is made possible by the second module’s automated data transmission to
administrators via a Wi-Fi module. Blood seekers can quickly access the third module, which
uses RFID for real-time inventory tracking and updates the blood stock availability on a web
based platform. According to experimental results, blood type detection was highly accurate
(96.5%), while real-time data transfer speeds varied according to network availability (fastest at
1.9s on 4G). Professionals working in blood organizations who participated in a usability
assessment reported increases in productivity, dependability, and managerial simplicity. This
automated blood bank system guarantees quicker and more effective emergency responses while
reducing waste, thereby enhancing the accuracy of blood availability.
