Development of a Mobile IoT Device for Supervision and Alert BPM Problems

Abstract:

The developmental supervision and alert device for heart problems is activated when the heart rate range presents an anomaly, that is, it is outside the established range that goes from 60 to 100 bpm in the resting state, inducing a heart problem known as cardiac arrhythmias. For real-time data, acquisition of heart rate variations is done through a MAX30100 pulse sensor (infrared sensor), also set at 660 nm to improve measurements. The device has an organic light-emitting diode (OLED) screen which indicates the values beats per minute (bpm) and oxygen saturation of blood (SpO2) of the person. Since the sensor should be located where the skin is thin, it is designed for the wrist of the hand. The communication module is the SIM808, which connects to the ThingSpeak platform using TCP/IP (Transmission Control Protocol/Internet Protocol) and then sends the data with the cardiac signals. Also, there are alerts of heart problems using Global System for Mobile Communications (GSM) network for sending the information of the acquired data by text message to the numbers registered in the device with GPS and bpm signal. Moreover, the very high performance of the power supply system employing a lithium polymer (LIPO) battery with 1800 mAh is accurate for the system.
