Wristband Heart Rate Measurement Module Heart Rate Monitor Heartbeat Pulse Sensor for Arduino
1. Module input voltage 3.3V—5V
2. Module output: AO output is analog signal, the oscilloscope can directly look at it, if it is processed by single chip, connect one AD analog signal acquisition port, it can collect heart rate data, DO output is pulse signal, high and low level.
3. Output amplitude: The output can be adjusted to reach 1/3 to VCC.
4. This module does not contain a wristband. The old anti-lost wristband can be searched for Taobao.
5. This module only has the code of arduino, and also has the single-chip code.
6.DO output pulse signal is the heartbeat output once high level, the internal comparison of the op amp, need to use potentiometer to adjust.
7. This module can not only measure the wrist, but also measure the fingertips. The fingertip capillary has more signals, which is no different from the 98-pin finger clip.
8. The wristband version of the heart rate measurement module, the heart rate finger-clip sensor measures the heart rate by the penetrating measurement method, and the wristband sensor measures the heart rate through the skin reflection type. Undoubtedly, the sensor output signal is smaller. The measurement is slightly more difficult.

Analog signal measured waveform:
Digital signal output measured waveform:
The digital signal output is essentially a high and low level, and the high-low level is detected by the single-chip microcomputer to realize (usually within 1 minute) pulse rate acquisition. Since the signal has been converted into a digital signal (high and low level), it is not required to go through the ADC conversion circuit to identify the level of the amplitude and is directly detected by the single-chip microcomputer, so the manufacturing cost is saved to some extent.
