Note

This command is only available in idle mode.

set_temperature_offset_parameters(offset, slope, time_constant, slot)

This command allows to compensate temperature effects of the design-in at customer side by applying custom temperature offsets to the ambient temperature. The compensated ambient temperature is calculated as follows: T_Ambient_Compensated = T_Ambient + (slope * T_Ambient) + offset Where slope and offset are the values set with this command, smoothed with the specified time constant. All temperatures (T_Ambient_Compensated, T_Ambient and offset) are represented in °C. There are 5 temperature offset slots available that all contribute additively to T_Ambient_Compensated. The default values for the temperature offset parameters are all zero, meaning that T_Ambient_Compensated is equal to T_Ambient by default. The parameters can be changed in any state of the device, i.e. both in idle mode and in measure mode.

Parameters:

• offset – Constant temperature offset scaled with factor 200 (T [°C] = value / 200).

• slope – Normalized temperature offset slope scaled with factor 10000 (applied factor = value / 10000).

• time_constant – The time constant determines how fast the new slope and offset will be applied. After the specified value in seconds, 63% of the new slope and offset are applied. A time constant of zero means the new values will be applied immediately (within the next measure interval of 1 second).

• slot – The temperature offset slot to be modified. Valid values are 0 .. 4. If the value is outside this range, the parameters will not be applied.

Note

This configuration is volatile, i.e. the parameters will be reverted to their default value of zero after a device reset.

Example:

sensor.set_temperature_offset_parameters(1, 10, 1, 0)

set_temperature_acceleration_parameters(k, p, t1, t2)

This command allows to set custom temperature acceleration parameters of the RH/T engine. It overwrites the default temperature acceleration parameters of the RH/T engine with custom values. This configuration is volatile, i.e. the parameters will be reverted to their default values after a device reset.

Parameters:

• k – Filter constant K scaled with factor 10 (K = value / 10).

• p – Filter constant P scaled with factor 10 (P = value / 10).

• t1 – Time constant T1 scaled with factor 10 (T1 [s] = value / 10).

• t2 – Time constant T2 scaled with factor 10 (T2 [s] = value / 10).

Note

The command is only available in idle mode.

Example:

sensor.set_temperature_acceleration_parameters(1, 1, 1, 1)

perform_forced_co2_recalibration(target_co2_concentration)

Execute the forced recalibration (FRC) of the CO₂. See the datasheet of the SCD4x sensor for details how the forced recalibration shall be used.

Parameters:

target_co2_concentration – Target CO₂ concentration [ppm] of the test setup.

Return correction:

Correction value as received from the SCD [ppm CO₂]. FRC correction [ppm CO₂] is calculated as follows: FRC = return_value - 0x8000 If the recalibration has failed this returned value is 0xFFFF.

Note

After power-on wait at least 1000 ms and after stopping a measurement 600 ms before sending this command. This command is not available in measure mode. The recalibration procedure will take about 500 ms to complete, during which time no other functions can be executed.

set_co2_sensor_automatic_self_calibration(status)

Sets the status of the CO₂ sensor automatic self-calibration (ASC). The CO₂ sensor supports automatic self calibration (ASC) for long-term stability of the CO₂ output. This feature can be enabled or disabled. By default it is enabled. This configuration is volatile, i.e. the parameter will be reverted to its default value after a device restart.

Parameters:

status – Set to true (0x0001) to enable or false (0x0000) to disable the automatic CO₂ measurement self calibration feature. High byte of uint16 is padding and always 0x00.

Note

This command is only available in idle mode.

Example:

sensor.set_co2_sensor_automatic_self_calibration(0)

get_co2_sensor_automatic_self_calibration()

The CO₂ sensor supports automatic self calibration (ASC) for long-term stability of the CO₂ output. This feature can be enabled or disabled. By default it is enabled. This configuration is volatile, i.e. the parameter will be reverted to its default value after a device restart.

Return padding:

Padding byte, always 0x00.

Return status:

Is set true (0x01) if the automatic self calibration is enabled or false (0x00) if the automatic self calibration is disabled.

Note

This command is only available in idle mode.

set_ambient_pressure(ambient_pressure)

The ambient pressure can be used for pressure compensation in the CO₂ sensor. Setting an ambient pressure overrides any pressure compensation based on a previously set sensor altitude. Use of this command is recommended for applications experiencing significant ambient pressure changes to ensure CO₂ sensor accuracy. Valid input values are between 700 to 1’200 hPa. The default value is 1013 hPa. This configuration is volatile, i.e. the parameter will be reverted to its default value after a device restart.

Parameters:

ambient_pressure – Ambient pressure [hPa] to be used for pressure compensation.

Note

This command can be used in any state of the device, i.e. both in idle mode and in measure mode.

Example:

sensor.set_ambient_pressure(1013)

get_ambient_pressure()

Gets the ambient pressure value. The ambient pressure can be used for pressure compensation in the CO₂ sensor.

Return ambient_pressure:

Currently used ambient pressure [hPa] for pressure compensation.

Note

This command can be used in any state of the device, i.e. both in idle mode and in measure mode.

set_sensor_altitude(altitude)

The sensor altitude can be used for pressure compensation in the CO₂ sensor. The default sensor altitude value is set to 0 meters above sea level. Valid input values are between 0 and 3000m. This configuration is volatile, i.e. the parameter will be reverted to its default value after a device reset.

Parameters:

altitude – Sensor altitude [m], valid input between 0 and 3000m.

Example:

sensor.set_sensor_altitude(0)

get_sensor_altitude()

Gets the current sensor altitude. The sensor altitude can be used for pressure compensation in the CO₂ sensor.

Return altitude:

Current sensor altitude [m].

Note

This command is only available in idle mode.

activate_sht_heater()

This command allows to use the inbuilt heater in SHT sensor to reverse creep at high humidity. This command activates the SHT sensor heater with 200mW for 1s. The heater is then automatically deactivated again. The “get_sht_heater_measurements” command can be used to check if the heater has finished. Wait at least 20s after this command before starting a measurement to get coherent temperature values (heating consequence to disappear).

Note

This command is only available in idle mode.

get_sht_heater_measurements()

Get the measured values when the SHT sensor heating is triggerd. If the heating is not finished, the returned humidity and temperature values are 0x7FFF.

Return humidity:

Value is scaled with factor 100: RH [%] = value / 100 Note: If this value is not available, 0x7FFF is returned.

Return temperature:

Value is scaled with factor 200: T [°C] = value / 200 Note: If this value is not available, 0x7FFF is returned.

read_device_status()

Reads the current device status. Use this command to get detailed information about the device status. The device status is encoded in flags. Each device status flag represents a single bit in a 32-bit integer value. If more than one error is present, the device status register value is the sum of the corresponding flag values. For details about the available flags, refer to the device status flags documentation in the data sheet.

Return device_status:

Device status (32 flags as an integer value). For details, please refer to the device status flags documentation in the datasheet.

Note

The status flags of type “Error” are sticky, i.e. they are not cleared automatically even if the error condition no longer exists. So they can only be cleared manually with the command “Read And Clear Device Status” or with a device reset. All other flags are not sticky, i.e. they are cleared automatically if the trigger condition disappears.

read_and_clear_device_status()

Reads the current device status (like command 0xD206 “Read Device Status”) and afterwards clears all flags.

Return device_status:

Device status (32 flags as an integer value) before clearing it. For details, please refer to the device status flags documentation.
