Abstract: Case1: Nowadays numerous persons are mislaying their life owing to heart attack and shortage of medical attention to patient at correct stage. This project is proposed on implementing heart rate observation and heart attack recognition system using IoT. An android application with built-in sensors was developed for patients. The patient has to carry this hardware with them. The heartbeat sensor will monitor the readings and send out them over the internet. The heartbeat limits can be fixed by the patient. The system will send an alert message if there is any change in the limit level fixed by the patient. Case 2: The second case study is over the years, there has been a sudden increase in the number of vehicles on the road. Traffic congestion is a growing problem that everyone faces in their daily life. Manual control of traffic by traffic police has not proved to be efficient. Also, the predefined set time for the signal at all circumstances (low and high traffic density) has not solved this problem. A model to effectively solve the above-mentioned problems by using Internet of Things (IoT) is proposed. The proposed work use cloud for internet-based computing, where different services such as server, storage and application are delivered for traffic management. A network of sensors is used to track the number of vehicles and the traffic congestion at the intersections on a road and rerouting will be done on the basis of the traffic density on the lanes of a road.
