IoT Based Remote Health Monitoring System Enhancing Two Way Communication

The integration of the Internet of Things (IoT) in healthcare has significantly improved remote patient monitoring by enabling continuous real-time tracking of vital signs and movement.This paper presents an IoT-based Real-Time Remote Patient Monitoring System enhanced with two-way communication to facilitate improved patient-caregiver interaction.The system is built around an ESP32 micro controller, which collects data from multiple sensors, including an ADXL345 accelerometer for fall detection, a DHT11 sensor for temperature and humidity monitoring, a 162 LCD provides real-time local feedback, while Wi-Fi connectivity ensures seamless remote data transmission.A key innovation of this system is its bidirectional communication capability, allowing caregivers to send alerts, emergency instructions, or medical guidance directly to the patient's device.This interaction is facilitated through a buzzer and display, ensuring timely responses and reducing delays in critical situations.The proposed system enhances traditional remote monitoring by integrating real-time sensor data acquisition with an interactive response mechanism.Experimental evaluations demonstrate its effectiveness in continuous health tracking, fall detection, and emergency alert transmission, making it a valuable solution for telemedicine, elderly care, and chronic disease management.
