Cargo Features

DHT11 has no features set by default.

[dependencies]

dwt = cortex-m

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
