The objectives of Developing an Online Blood Bank Management System with a Blood Bank Temperature Monitoring Device using Internet of Things Technology: a Case Study of Phutthaisong Hospital, Phutthaisong District, Buriram Province were: 1) to develop a program to manage the blood bank system (collecting blood - transfusing blood) for checking the temperature inside the blood bank and also for alerting when the temperature is higher or lower the controlled temperature to be displayed through the LINE Bot and 2) to evaluate the efficiency of the online blood bank system by medical technologists and computer science experts. The research instruments consisted of the Node MCU and Sensor DHT22 / AM2302. The set of programs with the developed equipment sets were used for sending the temperature control values within the blood bank refrigerator and the thermal cooler box used in exchanging nearly expiry blood. When the blood bank’s temperature was lower than 2 degrees Celsius or higher than 6 degrees Celsius, the temperature value was sent to the web server to record as Real-time data to Google Firebase with an alarm via the LINE Bot displaying the temperature value on the NETPIE Freeboard and emit alarms in the blood bank and thermal cooler box using Buzzer and the temperature can be checked through the LCD screen installed in the blood bank.
The results showed that the temperature can be recorded into the web application by using the device. The temperature value was real-time sent to LINE Bot. In the case that the temperature is not in the range of 2-6 degrees Celsius but the blood type is nearly outdated, there is a notification immediately made by the LINE Bot notifying the temperature and alerting about the blood type: 7 days before expiry date. In addition, the location of the thermal cooler box in a carrying vehicle can also tracked from the Real-time RFID Tag. The location of the vehicle can be seen when the box is moving along the route. The results from the system efficiency evaluation made by the medical technologists and computer science experts showed that in the overall aspect, the experts had the highest satisfaction level (4.43) towards the system. Moreover, the results of blood bank temperature monitoring device usage received the highest level of satisfaction (4.68).
