Smart Health Monitoring Wristband with Auto-Alert Function

Smart healthcare uses technology such as wearable devices and the Internet of Things to dynamically retrieve/access information, which is important for people who require continuous monitoring, that cannot be provided outside of medical facilities. The paper presents a smart health monitoring wristband that uses Arduino Nano 33 IoT with a built-in gyroscope and accelerometer module as the microcontroller, biomedical sensors like temperature sensor, pulse oximeter, heart rate sensor, and GSM/GPRS module. This prototype is developed for all age communities but can be especially useful to the elderly, people with special needs, and those with chronic illnesses. The hardware system is connected to the Blynk application using the microcontroller’s built-in WiFi module. The biomedical sensors measure the readings, and the data are uploaded onto the Blynk application interface for viewing. The Smart Health Monitoring Wristband enables real-time health monitoring to be done remotely and helps in improving emergency response time.
