Detailed Descriptions
These are used for the Decagon Devices CTD-10.
This depends on the EnviroDIY SDI-12 library and the SDI12Sensors super class.
Classes
- class DecagonCTD
- The Sensor sub-class for the Decagon CTD-10 conductivity, temperature, and depth sensor.
- class DecagonCTD_Cond
- The Variable sub-class used for the conductivity output from a Decagon CTD-10 3-in-1 water level sensor..
- class DecagonCTD_Temp
- The Variable sub-class used for the temperature output from a Decagon CTD-10 3-in-1 water level sensor..
- class DecagonCTD_Depth
- The Variable sub-class used for the depth output from a Decagon CTD-10 3-in-1 water level sensor..
Defines
- #define CTD_NUM_VARIABLES = 3
- Sensor::
_numReturnedValues; the CTD can report 3 values. - #define CTD_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for a Decagon CTD-10
- #define CTD_WARM_UP_TIME_MS = 500
- Sensor::
_warmUpTime_ms; maximum warm-up time in SDI-12 mode: 500ms. - #define CTD_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the CTD is stable as soon as it warms up (0ms stabilization). - #define CTD_MEASUREMENT_TIME_MS = 500
- Sensor::
_measurementTime_ms; maximum measurement duration: 500ms. - #define CTD_EXTRA_WAKE_TIME_MS = 0
- Extra wake time required for an SDI-12 sensor between the "break" and the time the command is sent. The CTD requires no extra time.
Conductivity
The conductivity variable from a Decagon CTD-10
- Range is 0 – 120 mS/cm (bulk)
- Accuracy is ±0.01mS/cm or ±10% (whichever is greater)
Construct a new DecagonCTD_
DecagonCTD_Cond(DecagonCTD* parentSense,
const char* uuid = "",
const char* varCode = CTD_
Parameters
parentSense
The parent DecagonCTD providing the result values.
uuid
A universally unique identifier (UUID or GUID) for the variable; optional with the default value of an empty string.
varCode
A short code to help identify the variable in files; optional with a default value of "CTDcond".
- #define CTD_COND_RESOLUTION = 1
- Decimals places in string representation; conductivity should have 1.
- #define CTD_COND_VAR_NUM = 2
- Sensor variable number; conductivity is stored in sensorValues[2].
- #define CTD_COND_VAR_NAME = "specificConductance"
- Variable name in ODM2 controlled vocabulary; "specificConductance".
- #define CTD_COND_UNIT_NAME = "microsiemenPerCentimeter"
- Variable unit name in ODM2 controlled vocabulary; "microsiemenPerCentimeter" (µS/cm)
- #define CTD_COND_DEFAULT_CODE = "CTDcond"
- Default variable short code; "CTDcond".
Temperature
The temperature variable from a Decagon CTD-10
- Range is -11°C to +49°C
- Accuracy is ±1°C
Construct a new DecagonCTD_
DecagonCTD_Temp(DecagonCTD* parentSense,
const char* uuid = "",
const char* varCode = CTD_
Parameters
parentSense

uuid
A universally unique identifier (UUID or GUID) for the variable; optional with the default value of an empty string.
varCode
A short code to help identify the variable in files; optional with a default value of "CTDtemp".
- #define CTD_TEMP_RESOLUTION = 2
- Decimals places in string representation; temperature should have 2.
- #define CTD_TEMP_VAR_NUM = 1
- Sensor variable number; temperature is stored in sensorValues[1].
- #define CTD_TEMP_VAR_NAME = "temperature"
- Variable name in ODM2 controlled vocabulary; "temperature".

- Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
- #define CTD_TEMP_DEFAULT_CODE = "CTDtemp"
- Default variable short code; "CTDtemp".
Water Depth
The water depth variable from a Decagon CTD-10
- Range is 0 to 5 m or 0 to 10 m, depending on model
- Accuracy is ±0.05% of full scale
