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 theSysTick
.InputOutputPin
-implementing type, for example anOutput<OpenDrain>
fromstm32f0xx_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
.
