PULSE WAVE SENSOR MODULE AND PULSE WAVE MEASUREMENT APPARATUS USING THE SAME

摘要

PURPOSE: A pulse wave sensor module and a pulse wave measurement apparatus using the same are provided to measure pulse wave having high precision by removing the external noise from a pulse wave signal at an output terminal. CONSTITUTION: A power terminal receives power from a power supply unit. A ground terminal is connected to a frame ground. A pulse wave detection sensor(100) detects a pulse wave and changes it into a voltage signal. A high pass filter(210, 220) removes noise. A first amplifier(300) amplifies the component of the pulse wave signal into a desired size.
