PBR

class app.workspace.devices.Phenometrics.classes.PBR.PBR(*args, **kwargs)

Bases: Connector

The PBR102-F™ is the next generation indoor photo bioreactor for outdoor algae production ponds, large-scale bioreactors, and teaching tools for algae laboratories. The PBR102-F is a fully programmable instrument that includes the FSL200 Full Spectrum light that simulates the colors of sunlight and promotes algae growth.

class PumpManager(device_id, connection: Connection)

Bases: object

Manager to control pumps.

discard()
start_pump()
stop_pump()
disableGUI()

Stop GUI of control software.

disconnect()

Terminate the connection between the application and physical device.

enableGUI()

Start GUI of control software.

flash_LED()

Triggers a flashing sequence and is used to physically identify the PBR. !!! random blank spaces complicate things. Is it like that also with “real” PBR?

Returns

True if was successful, False otherwise

get_cluster_name()

The name of the bioreactor array / cluster.

Returns

the cluster name

get_co2(raw, repeats)

No implemented.

get_hardware_address()

Get the MAC address of the PBR.

Returns

the MAC address

get_light_intensity(attribute)

Checks for current (max?) light intensity.

Items:

  • “intensity”: current light intensity (float) in μE,

  • “max”: maximal intensity (float) in μE,

  • “on”: True if light is turned on (bool)

Parameters

attribute – Given attribute device_id

Returns

The current settings structured in a dictionary.

get_o2(raw=True, repeats=5, wait=0)

Checks for concentration of dissociated O2.

Items:

  • “pulse”: current stirring in %,

  • “min”: minimal stirring in %,

  • “max”: maximal stirring in %,

  • “on”: True if stirring is turned on (bool)

Parameters

  • raw – True for raw data, False for data calculated according to temperature calibration

  • repeats – the number of measurement repeats

  • wait – waiting time between indivdevice_idual repeats

Returns

The current settings structured in a dictionary.

get_ph()

Get current pH (dimensionless.)

Returns

The current pH.

get_pump_params(pump)

Get parameters for given pump.

Parameters

pump – Given pump

Returns

The current settings structured in a dictionary.

get_pwm_settings()

Checks for current stirring settings.

Items:
