Detailed Descriptions
These are used for the discontinued Decagon Devices ES-2 Electrical Conductivity Sensor.
This depends on the EnviroDIY SDI-12 library and the SDI12Sensors super class.
Classes
- class DecagonES2
- The Sensor sub-class for the Decagon ES-2 sensor.
- class DecagonES2_Cond
- The Variable sub-class used for the conductivity output from a Decagon ES-2 electrical conductivity sensor.
- class DecagonES2_Temp
- The Variable sub-class used for the temperature output from a Decagon ES-2 electrical conductivity sensor.
Defines
- #define ES2_NUM_VARIABLES = 2
- Sensor::
_numReturnedValues; the ES2 can report 2 values. - #define ES2_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for a Decagon ES-2
- #define ES2_WARM_UP_TIME_MS = 250
- Sensor::
_warmUpTime_ms; maximum warm-up time in SDI-12 mode: 250ms. - #define ES2_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the ES2 is stable as soon as it warms up (0ms stabilization). - #define ES2_MEASUREMENT_TIME_MS = 250
- Sensor::
_measurementTime_ms; maximum measurement duration: 250ms. - #define ES2_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 ES-2 requires no extra time.
Conductivity
The conductivity variable from a Decagon ES-2
- Range is 0 – 120 mS/cm (bulk)
- Accuracy is ±0.01mS/cm or ±10% (whichever is greater)
Construct a new DecagonES2_
DecagonES2_Cond(DecagonES2* parentSense,
const char* uuid = "",
const char* varCode = ES2_
Parameters
parentSense
The parent DecagonES2 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 "ES2Cond".
- #define ES2_COND_RESOLUTION = 1
- Decimals places in string representation; conductivity should have 1.
- #define ES2_COND_VAR_NUM = 0
- Sensor variable number; conductivity is stored in sensorValues[0].
- #define ES2_COND_VAR_NAME = "specificConductance"
- Variable name in ODM2 controlled vocabulary; "specificConductance".
- #define ES2_COND_UNIT_NAME = "microsiemenPerCentimeter"
- Variable unit name in ODM2 controlled vocabulary; "microsiemenPerCentimeter" (µS/cm)
- #define ES2_COND_DEFAULT_CODE = "ES2Cond"
- Default variable short code; "ES2Cond".
Temperature
The temperature variable from a Decagon ES-2
- Range is -40°C to +50°C
- Accuracy is ±1°C
Construct a new DecagonES2_
DecagonES2_Temp(DecagonES2* parentSense,
const char* uuid = "",
const char* varCode = ES2_
Parameters
parentSense
The parent DecagonES2 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 "ES2Temp".
- #define ES2_TEMP_RESOLUTION = 2
- Decimals places in string representation; temperature should have 2.
- #define ES2_TEMP_VAR_NUM = 1
- Sensor variable number; temperature is stored in sensorValues[1].
- #define ES2_TEMP_VAR_NAME = "temperature"
- Variable name in ODM2 controlled vocabulary; "temperature".
- #define ES2_TEMP_UNIT_NAME = "degreeCelsius"
- Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
- #define ES2_TEMP_DEFAULT_CODE = "ES2Temp"
- Default variable short code; "ES2Temp".
