It would be helpful if there was a way for these people to monitor their heart. So we have a problem that is the way our project focuses on how we can utilize this problem and find a solution.We in this project are measuring the heartbeat. Keywords: 8051 Microcontroller Section, 7805 IC, Op-Amp, LCD Interfacing GSM Module I .INTRODUCTION The use of microcontroller is in every field even we can use it in the design and fabrication of biomedical equipment recently, the health care sensors are playing a vital role in hospitals. The patient monitoring systems is one of the major improvements because of its advanced technology. A wireless patient monitoring system to measure heartbeat of the patient by using embedded technology is developed.So we are here, just connecting the heartbeat sensor so that simultaneously we can monitor the patient’s condition and hence ruling out the use of the thermometer and other devices to check the condition of the patient. This project describes the design of a simple, low-cost microcontroller based heart rate measuring device with LCD output. Heart rate of the subject is measured from the index finger using heart beat module (the rate is then averaged and displayed on a text based LCD) II.CIRCUIT DIAGRAMS A.
