Most of the monitoring systems that are in use in today's world operate in offline mode, but it is in great need of a system to be designed so that the patient can be monitored remotely in real time. The paper consists of sensors that measure the heartbeat and body temperature of a patient that is controlled by the microcontroller. Both readings are displayed on the LCD monitor. The wireless system is used to transmit measured data to a remote location. The heartbeat sensor counts the heartbeat for the specific time interval and estimates the beats per minute while the temperature sensor measures the temperature and both data are sent to the microcontroller for transmission to the receiving end. Finally, the data is displayed on the LCD at the receiving end.

A heart rate monitor is a personal monitoring device that allows you to measure your heart rate in real time or record your heart rate for later study. It is used to a large extent by performers of various types of physical exercise. The heartbeat sensor provides a simple way to study heart function that can be measured based on the principle of the psycho-physiological signal used as a stimulus for the virtual reality system. The amount of blood in the finger changes with respect to time.

The sensor shines with a light lobe (a very bright little LED) through the ear and measures the light that is transmitted to the light dependent resistor. The amplified signal is inverted and filtered in the Circuit. In order to calculate heart rate based on blood flow to the fingertip, a heart rate sensor is mounted with the help of LM358 OP-AMP to monitor heartbeat pulses.
