Cargo Features

DHT11 has no features set by default.

[dependencies]
dht11 = { version = "0.3.1", features = ["dwt"] }
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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
