Detailed Descriptions
These are used for the Meter Hydros 21.
This depends on the EnviroDIY SDI-12 library and the SDI12Sensors super class.
Classes
- class MeterHydros21
- The Sensor sub-class for the Meter Hydros 21 conductivity, temperature, and depth sensor.
- class MeterHydros21_Cond
- The Variable sub-class used for the conductivity output from a Meter Hydros 21 3-in-1 water level sensor..
- class MeterHydros21_Temp
- The Variable sub-class used for the temperature output from a Meter Hydros 21 3-in-1 water level sensor..
- class MeterHydros21_Depth
- The Variable sub-class used for the depth output from a Meter Hydros 21 3-in-1 water level sensor..
Defines
- #define HYDROS21_NUM_VARIABLES = 3
- Sensor::
_numReturnedValues; the Hydros 21 can report 3 values. - #define HYDROS21_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for a Meter Hydros 21
- #define HYDROS21_WARM_UP_TIME_MS = 500
- Sensor::
_warmUpTime_ms; maximum warm-up time in SDI-12 mode: 500ms. - #define HYDROS21_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the Hydros 21 is stable as soon as it warms up (0ms stabilization). - #define HYDROS21_MEASUREMENT_TIME_MS = 1000
- Sensor::
_measurementTime_ms; maximum measurement duration: 1000ms. - #define HYDROS21_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 Hydros 21 requires no extra time.
Conductivity
The conductivity variable from a Meter Hydros 21
- Range is 0 – 120 mS/cm (bulk)
- Accuracy is ±0.01mS/cm or ±10% (whichever is greater)
Construct a new MeterHydros21_
MeterHydros21_Cond(MeterHydros21* parentSense,
const char* uuid = "",
const char* varCode = HYDROS21_
Parameters
parentSense
The parent MeterHydros21 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 "Hydros21cond".
- #define HYDROS21_COND_RESOLUTION = 1
- Decimals places in string representation; conductivity should have 1.
- #define HYDROS21_COND_VAR_NUM = 2
- Sensor variable number; conductivity is stored in sensorValues[2].
- #define HYDROS21_COND_VAR_NAME = "specificConductance"
- Variable name in ODM2 controlled vocabulary; "specificConductance".
- #define HYDROS21_COND_UNIT_NAME = "microsiemenPerCentimeter"
- Variable unit name in ODM2 controlled vocabulary; "microsiemenPerCentimeter" (µS/cm)
- #define HYDROS21_COND_DEFAULT_CODE = "Hydros21cond"
- Default variable short code; "Hydros21cond".
Temperature
The temperature variable from a Meter Hydros 21
- Range is -11°C to +49°C
- Accuracy is ±1°C
Construct a new MeterHydros21_
MeterHydros21_Temp(MeterHydros21* parentSense,
const char* uuid = "",
const char* varCode = HYDROS21_
Parameters
parentSense
The parent MeterHydros21 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 "Hydros21temp".
- #define HYDROS21_TEMP_RESOLUTION = 2
- Decimals places in string representation; temperature should have 2.
- #define HYDROS21_TEMP_VAR_NUM = 1
- Sensor variable number; temperature is stored in sensorValues[1].
- #define HYDROS21_TEMP_VAR_NAME = "temperature"
- Variable name in ODM2 controlled vocabulary; "temperature".
- #define HYDROS21_TEMP_UNIT_NAME = "degreeCelsius"
- Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
- #define HYDROS21_TEMP_DEFAULT_CODE = "Hydros21temp"
- Default variable short code; "Hydros21temp".
Water Depth
The water depth variable from a Meter Hydros 21
- Range is 0 to 5 m or 0 to 10 m, depending on model
- Accuracy is ±0.05% of full scale
Construct a new MeterHydros21_
MeterHydros21_Depth(MeterHydros21* parentSense,
