Abstract: With increasing air pollution & changing lifestyle health monitoring has become indispensible. The system proposed in this paper is an advanced solution for measuring & monitoring the important parameters such as heart beat rate, oxygen saturation level& storing the measured data on cloud memory through IOT (Internet of Things) .The gas sensor is used to measure the CO2 level of the breathing air and a pulse oximetry sensor intended for pulse detection & oxygen saturation level in a human body. The device includes an Arduino Uno for data processing and a Wi-Fi module for data transmission.

Keywords: Arduino Uno, pulse Oximetry sensor (MAX30100), Gas sensor (MQ135), Arduino IDE, Wi-Fi module (ESP8266).
