Detailed Descriptions
These are used for any sensor attached to an Atlas EZO pH circuit.
Classes
- class AtlasScientificpH
- The Sensor sub-class for the Atlas Scientific pH sensor.
- class AtlasScientificpH_pH
- The Variable sub-class used for the pH output from an Atlas Scientific EZO pH circuit.
Defines
- #define ATLAS_PH_I2C_ADDR = 0x63
- Default I2C address is 0x63 (99)
- #define ATLAS_PH_NUM_VARIABLES = 1
- Sensor::
_numReturnedValues; the Atlas EZO pH circuit can report 1 value. - #define ATLAS_PH_INC_CALC_VARIABLES = 0
- Sensor::
_incCalcValues; we don't calculate any additional values.
Sensor Timing
The sensor timing for an Atlas pH sensor
- #define ATLAS_PH_WARM_UP_TIME_MS = 850
- Sensor::
_warmUpTime_ms; the Atlas EZO pH circuit warms up in 850ms. - #define ATLAS_PH_STABILIZATION_TIME_MS = 0
- Sensor::
_stabilizationTime_ms; the Atlas EZO pH circuit is stable 0ms after warm-up (stable at completion of warm up). - #define ATLAS_PH_MEASUREMENT_TIME_MS = 1660
- Sensor::
_measurementTime_ms; the Atlas EZO pH circuit takes 1660ms to complete a measurement.
pH
The pH variable from an Atlas pH sensor
- Accuracy is ± 0.002
- Range is 0.001 − 14.000 (ATLAS_
PH_ RESOLUTION = 3) - Reported as dimensionless pH units
Construct a new AtlasScientificpH_
AtlasScientificpH_pH(AtlasScientificpH* parentSense,
const char* uuid = "",
const char* varCode = ATLAS_
Parameters
parentSense
The parent AtlasScientificpH 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 "AtlaspH".
- #define ATLAS_PH_RESOLUTION = 3
- Decimals places in string representation; pH should have 3 - resolution is 0.001.
- #define ATLAS_PH_VAR_NUM = 0
- Sensor variable number; pH is stored in sensorValues[0].
- #define ATLAS_PH_VAR_NAME = "pH"
- Variable name in ODM2 controlled vocabulary; "pH".
- #define ATLAS_PH_UNIT_NAME = "pH"
- Variable unit name in ODM2 controlled vocabulary; "pH" (dimensionless pH units)
- #define ATLAS_PH_DEFAULT_CODE = "AtlaspH"
- Default variable short code; "AtlaspH".
