Circuit The LM2904 is a simple circuit that can be an example of medical electronics , medical electronics in the op-amp integrated . LTM1550-01 photo sensor with heart rate, pulse sounding on the circuit with buzzer sound and led lighted warning is given. 4 pen batteries can be used as power supply. When you put your fingertip on the sensor, it detects the pulse and tells the heartbeat lightly and soundly. There are PCB drawings and parts list in the picture format of the project.
