@ -9,7 +9,7 @@ Overview
This sample periodically measures distance between vl53l0x sensor
and target. The result is displayed on the console.
It also shows how we can use the vl53l0x as a proximity sensor.
It shows the usage of all available channels including private ones.

This project outputs sensor data to the console. It requires a VL53L0X
sensor, which is present on the disco_l475_iot1 board.
