Now a day, many people in urban areas live alone in the room or home to satisfy their livelihood. Many people used to travel around the world to meet their profession. When they are alone, there is a chance that they may face health problems like cardiac arrest, pregnancy, epilepsy, paralysis, and other health issues. This may lead to death, if not attended. To avoid such a situation, a novel method is proposed in this paper, which discusses about the wearable sensor as a chain. This device measures the vital physiological parameters of human beings and the data is transmitted to the nearby hospital, so that the life of a patient can be saved by extending medical treatment.
