Recording readings from IR Sensor
#1
Hello guys,

my first post here so far.

I am using a Samung S9, equipped with the HRM-Sensor (pulse measuring, o2-saturation).

By accessing the the service mode i figured out that there might be some hidden potential if the signal from IR-sensor (and red) could be recorded.
Might be usefull for checking for
- surface roughness
- building a dew point meter (even there might be other ways for real electronics)
- determining of thickness of some materials (depending on IR-wavelength obsorbtion charackteristics).
- determining of thickness of some materials depending of theire reflectivitity.

As i couldn't figure out so far the infrared range, probaly something arround 900nm, there might be some possibilities for binary mixtures.

Have a nice weekend

Thanks for the suggestion, but I do not think that we can get low-level access. Even for the regular sensors we only use the API provided by Android (or iOS) which can be quite limiting compared to what the sensors actually could do.
