Development of Remote Health Monitoring System for Elderly using IoT and WSN

In today's rapidly evolving world, numerous people encounter difficulties in accessing medical services for minor health issues. To tackle this problem, we introduce a robust pulse monitoring system that also checks room temperature and humidity. This system harnesses cutting-edge technology to deliver live health and environmental information directly to medical professionals, allowing them to evaluate a patient's health remotely and offer immediate medical guidance or action. The setup includes essential hardware components like the NodeMCU ESP8266 microcontroller, the DHT11 sensor for temperature and humidity measurement, and a pulse sensor to monitor the patient's heart rate. The data from these sensors is sent to the cloud-based service ThingSpeak using the ThingESP library, making it available for healthcare providers to review and act upon. Moreover, the system incorporates TWILIO, a communication service, to facilitate WhatsApp messaging that alerts healthcare professionals instantly in the event of unusual health or environmental readings. This pioneering approach ensures that individuals can obtain prompt medical support and surveillance from their homes, enhancing proactive health management and ultimately improving health outcomes.
