| Abstract: | In this paper, hardware design of LCD display infrared pulsemeter is mainly described. Photoelectric sensor has been applied for the pulsemeter. The method of finger end photo electricity volume is used for detecting blood flow. Pulse wave signal has been amplify through the voltage amplification circuit, then comparator compares the input signal with the reference voltage and produces the logic signal on the fan-out. EM73461A microcomputer is used for calculating the number of heart beating in one minute. The pulsemeter also includes the function digital clock and count up/down timer. |
