Usage
The following sketch demonstrates a simple application of using the Ear-clip Heart Rate Sensor to measure heart rate.
Connect this module to the digital port D2 on Grove-Base shield. And connect Grove-LED to Digital port 4.
Plug the Base Shield into Arduino/Seeeduino.
Copy and paste code below to a new Arduino sketch.
Upload the code.
Make sure the sensor contacts your ear skin. This is the signal when we are measuring the heart rate:
In the first of the figures, which is a waveform diagram of the detected heartbeat, a high pulse comes when beating.
Note If the serial monitor return an error message, please change the position of the sensor.
