ECG Readings seem to be incorrect
I am running Example 2 with an Arduino UNO clone (Elegoo UNO R3). I did not use the QWIIC connector but instead manually connected:
GND->GND VCC->5V SDA->SDA SCL->SCL
I believe the default sampling rate is 200 hz, correct? I am touching the dry contacts. ECG_N with my thumb and index finger on the other side. ECG_P with my index finger.
Here is some of the data I am getting:
timestamp,ecg_measurement 5.0,0 10.0,0 15.0,-2072 20.0,-2072 25.0,-2072 30.0,-11205 35.0,-11205 40.0,-11205 45.0,-11205 50.0,-17871 55.0,-17871 60.0,-17871 65.0,-17871 70.0,-7851 75.0,-7851 80.0,-7851 85.0,-7851 90.0,-615
here is also a screenshot of the plot of the data
The sensor name is Maxim Integrated Products MAX86150EVSYS# Evaluation Board MAX86150 PPG/ECG Bio-Sensor Module.

i get ppg data properly but i does not get ecg data properly.
I am using this library. ProtoCentral_MAX86150_PPG_and_ECG_IC_library-1.0.2
