<![CDATA[Trouble with U118 / MAX30102 heart rate sensor]]>I'm having trouble getting the U118/MAX30102 heart rate sensor to function correctly. I'm using the checkForBeat() function in the Arduino IDE and Sparkfun 3010x library.

The sensor still detects heartbeats even if I place a small object on it, like an eraser!

I can make things better by playing with the sensor.setup() parameters, or by including a tiny delay() in the main loop, but I'd like to know if I'm doing it incorrectly.

Has anyone come across this problem with this sensor?
