In times of COVID we have special Covid 19 Quarantine centers setup in order to treat covid patients. Since covid is highly infectious it is very important to quarantine covid patients but at the same time doctors need to monitor health of covid patients too. With the increasing number of cases it is becoming difficult to keep a track on the health conditions of so many quarantined patients. The problems here are Doctors need to regularly monitor patient health and there are increasing number of patients for the doctors to monitor and also doctors are at risk of infection just for monitoring purpose. To Solve this issue we here design a IOT based health monitor system that allows for remotely monitoring of multiple covid patients over the internet. The system monitors patient heartbeat, temperature and blood pressure using a heartbeat sensor, temperature sensor and BP Sensor respectively. The system then transmits this data over the internet using wifi transmission by connecting to wifi internet connection. The data is transmitted and received over IOT by IOT Gecko platform to display data of patient remotely. The entire system is run by a microcontroller based circuitry. If any anomaly is detected in patient health pr if the patient presses the emergency help button on IOT device, an alert is sent over IOT remotely. This System allows Doctors to monitor patients remotely without risk of infection and Doctor gets instant alert in case of health fluctuations of emergency. In this paper, we have proposed ECG Monitoring System based on IoT (Internet of Things) Using this system doctors at hospital can analyse the critical parameters sent by this system. Doctors can also analyse the real time health related parameters of a patients which are not admitted in hospital. We have integrated ECG sensor in this system.
