YosemitechY520.h file

Contains the YosemitechY520 sensor subclass and the variable subclasses YosemitechY520_Cond and YosemitechY520_Temp.

These are for the Yosemitech Y520 4-pole conductivity sensor.

This depends on the YosemitechParent super class.

Documentation for the Modbus Protocol commands and responses can be found within the documentation in the YosemitechModbus library at: https://github.com/EnviroDIY/YosemitechModbus

Classes

class YosemitechY520
The Sensor sub-class for the Yosemitech Y520-A 4-electrode conductivity sensor.
class YosemitechY520_Cond
The Variable sub-class used for the conductivity output from a Yosemitech Y520-A 4-electrode conductivity sensor.
class YosemitechY520_Temp
The Variable sub-class used for the temperature output from a Yosemitech Y520-A 4-electrode conductivity sensor.

Defines

#define Y520_NUM_VARIABLES = 2
Sensor::_numReturnedValues; the Y520 can report 2 values.

Sensor Timing

The sensor timing for a Yosemitch Y520

#define Y520_WARM_UP_TIME_MS = 1600
Sensor::_warmUpTime_ms; time before sensor responds after power - 1600 ms.
#define Y520_STABILIZATION_TIME_MS = 10000
Sensor::_stabilizationTime_ms; time between "StartMeasurement" command and stable reading - 10sec (10,000ms).
#define Y520_MEASUREMENT_TIME_MS = 2700
Sensor::_measurementTime_ms; the Y520 takes ~2700ms to complete a measurement.

Conductivity

The conductivity variable from a Yosemitch Y520

  • Range is 1 µS/cm to 200 mS/cm
  • Accuracy is ± 1 % Full Scale

YosemitechY520_Cond(YosemitechY520* parentSense, const char* uuid = "", const char* varCode = Y520_COND_DEFAULT_CODE) explicit

Construct a new YosemitechY520_Cond object.

Parameters
parentSense The parent YosemitechY520 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 "Y520Cond".

#define Y520_COND_RESOLUTION = 1
Decimals places in string representation; conductivity should have 1.
#define Y520_COND_VAR_NUM = 0
Sensor variable number; conductivity is stored in sensorValues[0].
#define Y520_COND_VAR_NAME = "specificConductance"
Variable name in ODM2 controlled vocabulary; "specificConductance".
#define Y520_COND_UNIT_NAME = "microsiemenPerCentimeter"
Variable unit name in ODM2 controlled vocabulary; "microsiemenPerCentimeter" (µS/cm)
#define Y520_COND_DEFAULT_CODE = "Y520Cond"
Default variable short code; "Y520Cond".

Temperature

The temperature variable from a Yosemitch Y520

  • Range is 0°C to + 50°C
  • Accuracy is ± 0.2°C

YosemitechY520_Temp(YosemitechY520* parentSense, const char* uuid = "", const char* varCode = Y520_TEMP_DEFAULT_CODE) explicit

Construct a new YosemitechY520_Temp object.

Parameters
parentSense The parent YosemitechY520 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 "Y520Temp".

#define Y520_TEMP_RESOLUTION = 1
Decimals places in string representation; temperature should have 1 - resolution is 0.1°C.
#define Y520_TEMP_VAR_NUM = 1
Sensor variable number; temperature is stored in sensorValues[1].
#define Y520_TEMP_VAR_NAME = "temperature"
Variable name in ODM2 controlled vocabulary; "temperature".
#define Y520_TEMP_UNIT_NAME = "degreeCelsius"
Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
#define Y520_TEMP_DEFAULT_CODE = "Y520Temp"
Default variable short code; "Y520Temp".
