Abstract

The rapid proliferation of the Internet of Things (IoT) has created transformative opportunities in healthcare, particularly for continuous and remote patient monitoring. This paper presents the design, development, and experimental validation of an IoT-based healthcare monitoring system built on an Arduino Uno microcontroller. The system integrates four physiological sensors: an ECG module (AD8232) for cardiac signal acquisition, a MAX30100 SpO₂ sensor for blood oxygen saturation, an LM35 precision temperature sensor for body temperature, and an ADXL335 triaxial accelerometer for physical activity and fall detection. Three selector switches allow the user to choose which parameter is displayed on an I²C LCD in real time. A GSM900A module dispatches automated SMS alerts to registered caregivers whenever any parameter crosses predefined clinical thresholds, and a GPS module appends the patient’s geographic coordinates to each alert for emergency localisation. A NodeMCU ESP8266 Wi-Fi module bridges the Arduino Uno to the Adafruit IO cloud platform, enabling real-time dashboard visualisation, threshold-based notifications, and remote data access from any internet-connected device. Experimental results demonstrate multi-parameter monitoring accuracy with an ECG heart-rate MAE of 1.8 bpm, SpO₂ correlation r = 0.97, temperature MAE of 0.3°C, fall-detection sensitivity 94.2 %, end-to-end cloud latency 2.4 s, and SMS delivery within 8.7 s. The proposed system is cost-effective (below USD 40), low-power (≥7.5 h battery life), modular, and scalable for home healthcare, elderly monitoring, and rural telemedicine deployments.
