How can I check the distance ?

Well this is one of the last parts on electronics, it’s to see the distance from “me” to an obstacle.

I’m using this infrared sensors
Short distance (3-30cm)

Long distance (10-80cm)

Those sensors  give us  analog value for the distance, just to convert this value into a human understandable measure, but here is the result.

This circuit is just over the arduino. and with the sensor for short distance, (and also include a barometer but this will part of others projects)
For different materials (different reflection) give us different distances, but just for a few millimeters for our case will be ok.
