InSituRDO.h file

Contains the InSituRDO sensor subclass and the variable subclasses InSituRDO_Temp, InSituRDO_DOpct, and InSituRDO_DOmgL.

These are for the InSitu RDO PRO-X digital dissolved oxygen sensor.

This depends on the SDI12Sensors parent class.

Classes

class InSituRDO
The Sensor sub-class for the InSitu RDO PRO-X dissolved oxygen sensor.
class InSituRDO_DOmgL
The Variable sub-class used for the dissolved oxygen concentration output from a InSitu RDO PRO-X dissolved oxygen sensor.
class InSituRDO_DOpct
The Variable sub-class used for the dissolved oxygen percent saturation output from a InSitu RDO PRO-X dissolved oxygen sensor.
class InSituRDO_Temp
The Variable sub-class used for the temperature output from a InSitu RDO PRO-X dissolved oxygen sensor.
class InSituRDO_Pressure
The Variable sub-class used for the oxygen partial pressure output from a InSitu RDO PRO-X dissolved oxygen sensor.

Defines

#define INSITU_RDO_NUM_VARIABLES = 4
Sensor::_numReturnedValues; the RDO PRO-X can report 4 values.

Sensor Timing

The sensor timing for an InSitu RDO PRO-X.

None of these values are specified in the documentation for the sensor; this is all based on SRGD's testing.

#define INSITU_RDO_WARM_UP_TIME_MS = 125
Sensor::_warmUpTime_ms; ~125ms in SRGD tests.
#define INSITU_RDO_STABILIZATION_TIME_MS = 0
Sensor::_stabilizationTime_ms; the sensor is stable as soon as it can take a measurement.
#define INSITU_RDO_MEASUREMENT_TIME_MS = 850
Sensor::_measurementTime_ms; ~775 minimum.
#define INSITU_RDO_EXTRA_WAKE_TIME_MS = 0
Extra wake time required for an SDI-12 sensor between the "break" and the time the command is sent. We give the RDO an extra 10ms.

Dissolved Oxygen Concentration

The DO concentration variable from an InSitu RDO PRO-X

  • Range is 0 to 50 mg/L concentration
  • Accuracy:
    • ± 0.1 mg/L from 0 to 8 mg/L
    • ± 0.2 mg/L of reading from 8-20 mg/L
    • ± 10% of reading from 20-50 mg/L

InSituRDO_DOmgL(InSituRDO* parentSense, const char* uuid = "", const char* varCode = INSITU_RDO_DOMGL_DEFAULT_CODE) explicit

Construct a new InSituRDO_DOmgL object.

Parameters
parentSense The parent InSituRDO providing the result values.
