pub struct SCD30 { /* fields omitted */ }

Structo encapsulating all the data required for the scd30 sensor

Implementations

impl SCD30

pub fn new() -> Result<SCD30, Error>

creates a new sensor with the default I2C address 0x61

pub fn from_slave_address(slave_address: u16) -> Result<SCD30, Error>

Generates the sensor from an arbitrary slave address the default address is 0x61

pub fn get_bus_speed(&mut self) -> Result<u32, Error>

Reads the I2C bus speed

pub fn set_measure_interval(
    &mut self,
    interval_seconds: u16
) -> Result<(), Error>

Sets the measure interval in seconds. The sensor default interval is 2s.

pub fn read_firmware_version(&mut self) -> Result<String, Error>

Reads the sensor firmware version.

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

Reads the currently set measurement interval in seconds

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

Reads the measurement values temperature, humidity and CO2 concentration from the sensor

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

Gets the temperature in degree Celsius. If the value is older than measure interval, it reads the value from the sensor.

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

Gets the humidity in percent. If the value is older than measure interval, it reads the value from the sensor.

pub fn co2(&mut self) -> Result<f32, Error>

Gets the CO2 concentration in ppm. If the value is older than measure interval, it reads the value from the sensor.

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

Enables the sensor self calibration mechanism. See also sensor documentation

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

Disables the sensor self calibration. See also sensor documentation.

pub fn set_altitude_compensation(
    &mut self,
    altitude_mum: u16
) -> Result<(), Error>

Sets the altitude compensation in meters above sea level.

pub fn set_forced_recalibration(
    &mut self,
    real_co2_ppm: u16
) -> Result<(), Error>

Force sensor recalibration based on the given CO2 concentration.

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

Sets a temperature offset to compensate heat from a nearby device.

pub fn start_with_alt_comp(&mut self, pressure_mbar: u16) -> Result<(), Error>

Starts the measurement in the sensor based on the given altitude compensation in millibar.

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

Starts the measurement in the sensor.

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

Stops the sensor

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

Soft reset the sensor

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

True if there is new measurement data to read from the sensor.
