Kumar Gala 5d36157c7c sensors: Remove unnecessary Kconfig setting of sensors Sensor Kconfig sybmols should be enabled if CONFIG_SENSOR=y and the devicetree node for the sensor is enabled. We can remove explicitly enabling specific sensor drivers in .conf files. Signed-off-by: Kumar Gala <galak@kernel.org>		2022-07-25 15:18:56 +02:00

MAX30101 Heart Rate Sensor
##########################

Overview
********

A sensor application that demonstrates how to poll data from the max30101 heart
rate sensor.

Building and Running
********************

This project configures the max30101 sensor on the :ref:`hexiwear_k64` board to
enable the green LED and measure the reflected light with a photodiode. The raw
ADC data prints to the console. Further processing (not included in this
sample) is required to extract a heart rate signal from the light measurement.
