This is a follow-up on the previous post on the heart beat sensor MAX30102. The problem encountered previously was the death of the sensor with no explanations. We tested out a new sensor on the code and determined two possible causes. 

Firstly, we based ourselves on code online which uses an Arduino with a 3.6V input. After reading the specifications we observed that the sensor can be submitted to a voltage of min 1.7V and max 2V with a suggested 1.8V input. 

Secondly, the sensor should be tailored to the different skin and the location where we put the sensor. The intensity of the light emitted should be changed in order to find the best possible results. This needs to be experimented on to find the best solution.
