What: /sys/bus/iio/devices/iio:deviceX/in_proximity_nearlevel Date: March 2020 KernelVersion: 5.7 Contact: linux-iio@vger.kernel.org Description: Near level for proximity sensors. This is a single integer value that tells user space when an object should be considered close to the device. If the value read from the sensor is above or equal to the value in this file an object should typically be considered near. What: /sys/bus/iio/devices/iio:deviceX/sensor_sensitivity Date: March 2014 KernelVersion: 3.15 Contact: linux-iio@vger.kernel.org Description: Proximity sensors sometimes have a controllable amplifier on the signal from which time of flight measurements are taken. The appropriate values to take is dependent on both the sensor and its operating environment: * as3935 (0-31 range) 18 = indoors (default) 14 = outdoors
