Heart Rate and Body Temperature Monitoring Based on Android Operating System

The heart is a vital human organ. Heart monitoring is needed to maintain health. At present, the device used to measure heart rate is a stethoscope. The body’s health can also be indicated by body temperature. The instrument for measuring body temperature is a thermometer. However, it is manual and involves humans in the measurement that may lead to measurement errors. To reduce measurement errors the result of the heart rate and body temperature monitoring was displayed on android and the web using Bluetooth HC-06 communication. This device also used the MLX90614 pulse sensor and infrared sensor connected to Arduino Pro Mini and Android Studio. Pulse sensor will detect heart rate, and infrared signal will detect body temperature. The sensor readings are sent to Arduino to be processed with fuzzy decision tree algorithm and it produces an output according to the conditions measured. The results of measurements are displayed on the Android interface via Bluetooth communication. The data are stored in a database and displayed on the application in a graphical form.
