Mr.B.Vamsy Krishna,S. Abhinaya Sri,P. Jeevana Sree,S. Poorneswari,Ch. Kalyan Babu 03 03 The proposed system is an IoTbased Patient Health Monitoring System designed to continuously track essential physiological parameters of a patient in real time It incorporates a heartbeat sensor blood pressure sensor and ECG sensor to monitor pulse rate blood pressure and cardiac signals while a DHT11 sensor measures the surrounding temperature and humidity All sensor data is collected and processed by an Arduino UNO which acts as the main control unit of the system A NodeMCU ESP8266 module transmits the processed data to the ThingSpeak cloud platform enabling doctors and caregivers to remotely access and monitor the patients health condition from any location For local observation a 162 LCD is used to display live readings at the patients side In addition a buzzer is integrated to provide immediate alerts whenever any of the measured parameters exceed preset threshold values ensuring quick response during emergencies The system operates on a regulated 5V power supply supported by a 12V 1A adapter to guarantee stable performance This smart solution minimizes the need for continuous manual checking enhances patient safety and is highly suitable for hospitals home healthcare and elderly care monitoring Copyright (c) Journal of Science Engineering Technology and Management Science.
