IoT-Based Health Monitoring System Using Raspberry Pi Pico W and GSM Module

The integration of IoT technologies in healthcare has significantly enhanced the ability to monitor and manage patient health remotely. This project leverages the Raspberry Pi Pico W, a microcontroller with built-in Wi-Fi, to develop a comprehensive health monitoring system. The system incorporates a DHT11 sensor to measure ambient temperature and a heartbeat sensor to monitor the patient's pulse rate.

Data collected from these sensors is transmitted to the IoT platform ThingSpeak for real-time analysis and visualization. When the system detects that temperature or heartbeat values exceed predefined threshold limits, it triggers alerts. To ensure effective communication, the system is equipped with a GSM module that sends text message notifications to authorized personnel, providing immediate alerts regardless of internet connectivity.

This health monitoring system not only benefits from the Raspberry Pi Pico W’s connectivity features but also from the GSM module's capability to deliver critical messages directly to mobile devices. This dual-alert mechanism enhances patient safety by ensuring that necessary notifications reach healthcare providers promptly, thereby facilitating quick interventions and improving overall patient care.
