DHT11/DHT22 sensor driver

This library provides a platform-agnostic driver for the DHT11 and DHT22 sensors.

Use one of two functions dht11::Reading::read and dht22::Reading::read to get a reading.

Usage

The only prerequisites are an embedded-hal implementation that provides:

• Delay-implementing type, for example Cortex-M microcontrollers typically use the SysTick.
• InputOutputPin-implementing type, for example an Output<OpenDrain> from stm32f0xx_hal.
  • Note that you'll almost certainly need to configure your pin as open drain. See #23 for some discussion.

See the stm32f042 example for a commented example of how to use the library.

Release mode may be required

Compiling in debug mode may disturb the timing-sensitive parts of this crate and ultimately lead to failure. In this case, you will likely receive a Timeout error. Try compiling with --release instead.

Tests

To run the tests, use something like cargo test --lib --target x86_64-unknown-linux-gnu.
