Development of IoT Heartbeat and Body Temperature Monitoring System for Community Health Volunteer

Every community in Thailand has supporting groups that are responsible for routine health monitoring of all community members to reduce doctor and nurse works. IoT heartbeat and body temperature monitoring system is designed for them when they visit each house for a regular health checkup. The system consists of two parts, portable measuring device and android application. The portable measuring device can measure the heart rate and body temperature. The device uses Arduino board that connects to the heartbeat and temperature sensor. It shows the heartbeat and temperature readings on LCD display and at the same time sends them to ThingSpeak IoT platform in real-time via Wi-Fi. When both readings are uncommon, the system will send the notification to Line application. The android application can keep track of all measuring devices and community member records by using Firebase database. It also shows graph of heart rate and temperature values in real-time and in the specified interval time, e.g., a day or a week. In the paper, the different types of sensors are compared to see the different performances. The evaluation of the system performance by 3 computer experts found that the developed system was in good level (x̅=4.47) and the evaluation of the system usage satisfaction by 40 community health volunteers found that the overall satisfaction was in good level (x̅=4.47).
