We aim to propose a simple design of a pulse meter. Pulse measurement is primarily based on a single-chip microcontroller unit (MCU) that receives the signal of a fingertip pulse and converts it into electrical signals using an infrared sensor. The signals are amplified and filtered by the proposed circuit and software. The pulse meter displays the measured value on a liquid crystal display (LCD) 1602 screen. The result with the prototype pulse meter with the proposed circuit design and software shows an accuracy of 98.9−102.5% and a relative standard deviation of 0.82−0.90%. The proposed design provides the basis for developing further improved pulse meters that are appropriate for mobile devices.Corresponding author: Xuan-Jun Dai
