[OK ] I ran the MAX30100_Tester and I'm going to paste the output down below
[OK ] I filled in all the details of my setup down below
Description of the issue
I am using Max30100 and the sensor reads the data correctly and bpm and spo2 values are correct before uploading to thingspeak. After uploading to thingspeak, bpm and spo2 values only show "0".
Output from MAX30100_Tester example
Details of my setup
The wiring is as below:
MAX30100 ---> Arduino
VIN 5V
SCL A5 with 4.7k ohm pullup resistor
SDA A4 with 4.7k ohm pullup resistor
INT 3.3V
GND GND
