摘要
脉搏测量是指检测脉博的有无,使用的传感器是红外接收二极管和红外发射二极管。信号经过放大后,送入单片机计数测量。为了克服干扰,设计了低通放大器。
The pulse measurement is to detect pulses and pulseless.The sensor is infrared receiving diode and infrared emission diode. The signals are amplified followed by being sent to microcotroller for countering. The low-pass filter amplifier for conquering disturbs was designed.
