Struct Scd30

pub struct Scd30<I2C> { /* private fields */ }

Interface for the SCD30 CO2 sensor by Sensirion.

Implementations

impl<I2C: I2c<Error = I2cErr>, I2cErr: Error> Scd30<I2C>

pub fn new(i2c: I2C) -> Self

Create a new SCD30 interface.

pub fn trigger_continuous_measurements( &mut self, pressure_compensation: Option<AmbientPressureCompensation>, ) -> Result<(), Scd30Error<I2cErr>>

Start continuous measurements. This is stored in non-volatile memory. After power-cycling the device, it will continue measuring without being send a measurement command. Additionally an AmbientPressure value can be send, to compensate for ambient pressure. Default ambient pressure is 1013.25 mBar, can be configured in the range of 700 mBar to 1400 mBar.

pub fn stop_continuous_measurements(&mut self) -> Result<(), Scd30Error<I2cErr>>

Stop continuous measurements.

pub fn set_measurement_interval( &mut self, interval: MeasurementInterval, ) -> Result<(), Scd30Error<I2cErr>>

Configures the measurement interval in seconds, ranging from to 2s to 1800s.

pub fn get_measurement_interval( &mut self, ) -> Result<MeasurementInterval, Scd30Error<I2cErr>>

Reads out the configured continuous measurement interval

pub fn is_data_ready(&mut self) -> Result<DataStatus, Scd30Error<I2cErr>>

Checks whether a measurement is ready for readout.

pub fn read_measurement(&mut self) -> Result<Measurement, Scd30Error<I2cErr>>

Reads out a Measurement from the sensor.

pub fn set_automatic_self_calibration( &mut self, setting: AutomaticSelfCalibration, ) -> Result<(), Scd30Error<I2cErr>>

Activates or deactivates automatic self-calibration.

pub fn get_automatic_self_calibration( &mut self, ) -> Result<AutomaticSelfCalibration, Scd30Error<I2cErr>>

Reads out the current state of the automatic self-calibration.

pub fn set_forced_recalibration( &mut self, frc: ForcedRecalibrationValue, ) -> Result<(), Scd30Error<I2cErr>>

Configures the forced re-calibration (FRC) value to compensate for sensor drift. The value can range from 400 ppm to 2000 ppm.

pub fn get_forced_recalibration( &mut self, ) -> Result<ForcedRecalibrationValue, Scd30Error<I2cErr>>

Reads out the configured value of the forced re-calibration (FRC) value.

pub fn set_temperature_offset( &mut self, offset: TemperatureOffset, ) -> Result<(), Scd30Error<I2cErr>>

Configures the temperature offset to compensate for self-heating electric components. The value can range from 0.0 °C to 6553.5 °C.

pub fn get_temperature_offset( &mut self, ) -> Result<TemperatureOffset, Scd30Error<I2cErr>>

Reads out the configured temperature offset.

pub fn set_altitude_compensation( &mut self, altitude: AltitudeCompensation, ) -> Result<(), Scd30Error<I2cErr>>

Configures the altitude compensation. The value can range from 0 m to 65535 m above sea level.

pub fn get_altitude_compensation( &mut self, ) -> Result<AltitudeCompensation, Scd30Error<I2cErr>>

Reads out the configured altitude compensation.

pub fn read_firmware_version( &mut self, ) -> Result<FirmwareVersion, Scd30Error<I2cErr>>

Reads out the version of the firmware deployed on the sensor.

pub fn soft_reset(&mut self) -> Result<(), Scd30Error<I2cErr>>

Executes a soft reset of the sensor.

pub fn shutdown(self) -> I2C

Consumes the sensor and returns the contained I2C peripheral.
