ECG Readings seem to be incorrect

[lambo81]

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

Hi, let me see your code for getting ECG data

[vivekkumar1912]

The sensor name is Maxim Integrated Products MAX86150EVSYS# Evaluation Board MAX86150 PPG/ECG Bio-Sensor Module.

sample rate of both is 200

i get ppg data properly but i does not get ecg data properly.

I am using this library.
