Objective: The main objective is to develop a smart device, which is integrated in order to help the aged people during the time of medical emergency situations using Internet of Things (IoT). Methods: The technical methodology implemented is to develop a smart device which works on the basic support of the android application. The device serving people in danger is built using the smart phone applications, Bluetooth transmitter and receiver and microcontroller (Kiel micro vision). Kiel micro vision is an integrated development environment used to create software to be run on embedded system (like a microcontroller). Effective Quality of Service (QoS) is achieved using the concept of IoT. Findings: The concept of IoT is implemented in order to develop an environment which provides a unique way to communicate and transfer data from one end to the other end. The Internet of Things is a new way implementation in the field of medical background, which acts as a media for information retrieval from physical world to digital world, which is enhanced by the support of android platform. Hence the embedded system together constitutes two devices: Stationary device and a Movable device. The Stationary device is inbuilt with an ATMEL Microcontroller, RF Receiver, Bluetooth module, Step-down transformer, an LCD display, Voltage regulator, resistors and Capacitors. The movable device is inbuilt with two buttons along with a RF Transmitter. Application: The smart device for alerting a person’s critical health condition is of good use as it is less expensive and easy to handle, since the people in need are helped in the right time. Moreover this system can also alert our neighborhood even in situations like robbery. The Stationary device which the person is handling can be made as a device attached to human body, say a watch. The size of the device is made smaller, even though the cost becomes higher. Call features also added instead of message feature because everyone looks on text message.
