Implementations

impl<I2C, D, E> Scd4x<I2C, D>

where I2C: I2c<Error = E>, D: DelayNs,

pub fn new(i2c: I2C, delay: D) -> Self

pub fn destroy(self) -> I2C

pub fn start_periodic_measurement(&mut self) -> Result<(), Error<E>>

Start periodic measurement, signal update interval is 5 seconds. This command is only available in idle mode.

pub fn stop_periodic_measurement(&mut self) -> Result<(), Error<E>>

Stop periodic measurement and return to idle mode for sensor configuration or to safe energy. This command is only available in measurement mode.

pub fn sensor_output(&mut self) -> Result<RawSensorData, Error<E>>

Read raw sensor data

pub fn measurement(&mut self) -> Result<SensorData, Error<E>>

Read converted sensor data

pub fn temperature_offset(&mut self) -> Result<f32, Error<E>>

Get sensor temperature offset

pub fn set_temperature_offset(&mut self, offset: f32) -> Result<(), Error<E>>

Set sensor temperature offset

pub fn altitude(&mut self) -> Result<u16, Error<E>>

Get sensor altitude in meters above sea level.

pub fn set_altitude(&mut self, altitude: u16) -> Result<(), Error<E>>

Set sensor altitude in meters above sea level.

pub fn set_ambient_pressure( &mut self, pressure_hpa: u16 ) -> Result<(), Error<E>>

Set ambient pressure to enable continious pressure compensation

pub fn forced_recalibration( &mut self, target_co2_concentration: u16 ) -> Result<u16, Error<E>>

Perform forced recalibration

pub fn automatic_self_calibration(&mut self) -> Result<bool, Error<E>>

Get the status of automatic self-calibration

pub fn set_automatic_self_calibration( &mut self, enabled: bool ) -> Result<(), Error<E>>

Enable or disable automatic self-calibration

pub fn start_low_power_periodic_measurements(&mut self) -> Result<(), Error<E>>

Start low power periodic measurements

pub fn data_ready_status(&mut self) -> Result<bool, Error<E>>

pub fn persist_settings(&mut self) -> Result<(), Error<E>>

Save settings to non-volatile memory

pub fn serial_number(&mut self) -> Result<u64, Error<E>>

Get 48-bit serial number

pub fn self_test_is_ok(&mut self) -> Result<bool, Error<E>>

End-of-line test to confirm sensor functionality.

pub fn factory_reset(&mut self) -> Result<(), Error<E>>

Initiates the reset of all configurations stored in the EEPROM and erases the FRC and ASC algorithm history.

pub fn reinit(&mut self) -> Result<(), Error<E>>

The reinit command reinitializes the sensor by reloading user settings from EEPROM.
