Struct esp_ward::peripherals::bme280::Bme280Sensor

pub struct Bme280Sensor {
    pub inner: BME280<I2C<'static, I2C0>>,
    pub delay: Delay,
}

A sensor instance for the BME280 that provides access to temperature, humidity, and pressure readings.

Fields

inner: BME280<I2C<'static, I2C0>>

The internal BME280 driver from the bme280 crate used over I2C.

delay: Delay

A delay provider for timing-dependent operations.

Trait Implementations

impl HumiditySensor for Bme280Sensor

fn get_humidity(&mut self) -> Result<f32, PeripheralError>

Reads the current relative humidity from the BME280 sensor.

Returns

Returns an Ok(f32) representing the relative humidity in percentage if the read is successful, or Err(PeripheralError::ReadError) if the humidity cannot be read.

impl I2cPeriph for Bme280Sensor

fn create_on_i2c( bus: I2C<'static, I2C0>, delay: Delay ) -> Result<Self::Returnable, PeripheralError>

Creates a new instance of the BME280 sensor using the provided I2C bus.

Arguments

• bus - The I2C bus to use for communication with the sensor.
• delay - A delay provider for timing-dependent operations.

Returns

Returns an Ok(Bme280Sensor) if the sensor is successfully initialized, or Err(PeripheralError::InitializationFailed) if the sensor cannot be initialized.

type Returnable = Bme280Sensor

impl PressureSensor for Bme280Sensor

fn get_pressure(&mut self) -> Result<f32, PeripheralError>

Reads the current atmospheric pressure from the BME280 sensor.

Returns

Returns an Ok(f32) representing the pressure in hPa (hectopascals) if the read is successful, or Err(PeripheralError::ReadError) if the pressure cannot be read.

impl TemperatureSensor for Bme280Sensor

fn get_temperature(&mut self) -> Result<f32, PeripheralError>

Reads the current temperature from the BME280 sensor.

Returns

Returns an Ok(f32) representing the temperature in degrees Celsius if the read is successful, or Err(PeripheralError::ReadError) if the temperature cannot be read.

impl UnifiedData for Bme280Sensor

fn read(&mut self, _delay: Delay) -> Result<Self::Output, PeripheralError>

Reads the current relative humidity, temperature and pressure from the BME280 sensor.

Returns

Returns an Ok((f32, f32, f32)) representing the relative humidity(percentage), temperature(celsious) and pressure(hPa) if the read is successful, or Err(PeripheralError::ReadError) if the data from sensor cannot be read.

type Output = (f32, f32, f32)
