Now the technology of a day is working over time, fully occupied the lifestyle of human beings. It is used every time in our daily life to meet our requirements. We are using different sensors for different applications sometimes we can even use the same sensors differently for different applications. Not only can we increase the speed of life but also increase security with good ideas making use of advanced technology. In this project we are making use of technology to detect serious health problems so that efficient medical service

It can be provided to the patient at the appropriate time. The operation of this device is based on the truth that the blood circulates through each heartbeat that can be detected using a circuit formed by the combination of an LDR and an LED. Depending on the rate of blood circulation per second, the heart rate per minute is calculated. This device consists of a microcontroller that takes the input from the heartbeat sensor and calculates the heart rate of the patient. The microcontroller also assumes the responsibility of sending messages through the GSM modem. The main objective of this project   Real-time monitoring of a person's health status. The location of patients is easily tracked using the GPS-based positioning system. Send alerts in the form of SMS messages to the emergency ambulance.
