Expand description

AHT40 sensor.

Implementations§

Source§

impl<I: I2c, D: DelayNs> Aht40<I, D>

Source

pub fn new(addr: u8, i2c: I, delay: D) -> Self

Requires >= 5ms (datasheet says this, but I recommend 100ms like AHT30) after power-up, this function includes no delay, callers must ensure this timing.

Source

pub fn read(&mut self, checksum: bool) -> Result<Aht40Measurement, SensorError>

Measure then read sensor, takes >= 80ms to be done. Enable checksum is recommended.
