Struct Dht22 

Source 
pub struct Dht22<Pin, Timer>
where
    Pin: IOPin,
    Timer: MicroTimer,
{ /* private fields */ }
Expand description

Represents a DHT22 sensor connected to a pin.

Implementations§

Source§

impl<Pin, Timer> Dht22<Pin, Timer>
where Pin: IOPin, <Pin as IOPin>::DeviceError: Debug, Timer: MicroTimer,

Source

pub fn new(pin: Pin, clock: Timer) -> Self

Construct a new representation of the DHT22 sensor. Construction is cheap as long as the pin and clock are cheap to move.

Source

pub fn read(&mut self) -> Result<SensorReading, DhtError<Pin::DeviceError>>

Attempt one read from the DHT22 sensor. Between subsequent reads from the same sensor at least 2 seconds should pass to avoid erratic readings. Reading to early after startup may also result in failure to read.
