+#### Footprint OneWire
+
+This library depends (is build) upon the **OneWire** library of Paul Stoffregen.
+- https://github.com/PaulStoffregen/OneWire - the reference imho.

+In issue [#31](https://github.com/RobTillaart/DS18B20_RT/issues/31) the footprint of 
+the OneWireNG seems to be smaller when build on platformIO.
