Development of IoT Based Healthcare Monitoring System

In this era, the Internet of Things (IoT) has mainly been used in the advancement of technology since the Internet has become part of our daily life and one of the smart inventions to implement with IoT is a health monitoring system. Therefore, a healthcare monitoring system based on IoT with multiple sensors and a smart security system is introduced in this paper. The system was designed with a pulse sensor for the heartbeat, an infrared thermometer sensor for body temperature, and a DHT11 sensor for humidity and room temperature. The sensors relied on the Arduino used to monitor the patient's condition and the collected data were displayed on the LCD with the implementation of the Wi-Fi module, the data was sent and stored to ThingSpeak (cloud platform). If the sensor read the abnormal reading from the patient, a short message service (SMS) was sent to the cell phone through Global System for Mobile (GSM) to notify immediately the family or doctor. The performance of the pulse sensor and temperature sensor was tested with various experiments. Based on the comparison of sensors with the existing device, the percentage error for the infrared thermometer sensor was 1.2%.
