Yosemitech Y514 Wipered Chlorophyll Sensor module

Classes for the Yosemitech Y514 chlorophyll sensor with wiper.

Sensor Datasheet

Sensor Constructor

YosemitechY514(byte modbusAddress, Stream* stream, int8_t powerPin, int8_t powerPin2 = -1, int8_t enablePin = -1, uint8_t measurementsToAverage = 1)

Construct a new Yosemitech Y514 object.

Parameters
modbusAddress The modbus address of the sensor.
stream An Arduino data stream for modbus communication. See notes for more information on what streams can be used.
powerPin The pin on the mcu controlling power to the Y514. Use -1 if it is continuously powered.
powerPin2 The pin on the mcu controlling power to the RS485 adapter, if it is different from that used to power the sensor. Use -1 or omit if not applicable.
enablePin The pin on the mcu controlling the direction enable on the RS485 adapter, if necessary; use -1 or omit if not applicable.
measurementsToAverage The number of measurements to take and average before giving a "final" result from the sensor; optional with a default value of 1.


Example Code

The Yosemitech Y514 chlorophyll sensor is used in the menu a la carte example.

#include <sensors/YosemitechY514.h>

// NOTE: Extra hardware and software serial ports are created in the "Settings
// for Additional Serial Ports" section

byte         y514ModbusAddress = 0x14;  // The modbus address of the Y514
const int8_t y514AdapterPower =
    sensorPowerPin;  // RS485 adapter power pin (-1 if unconnected)
const int8_t  y514SensorPower = A3;  // Sensor power pin
const int8_t  y514EnablePin   = -1;  // Adapter RE/DE pin (-1 if not applicable)
const uint8_t y514NumberReadings = 5;
// The manufacturer recommends averaging 10 readings, but we take 5 to minimize
// power consumption

// Create a Y514 chlorophyll sensor object
YosemitechY514 y514(y514ModbusAddress, modbusSerial, y514AdapterPower,
                    y514SensorPower, y514EnablePin, y514NumberReadings);

// Create chlorophyll concentration and temperature variable pointers for the
// Y514
Variable* y514Chloro = new YosemitechY514_Chlorophyll(
    &y514, "12345678-abcd-1234-ef00-1234567890ab");
Variable* y514Temp =
    new YosemitechY514_Temp(&y514, "12345678-abcd-1234-ef00-1234567890ab");

Classes

class YosemitechY514
The Sensor sub-class for the Yosemitech Y514 sensor.
class YosemitechY514_Chlorophyll
The Variable sub-class used for the chlorophyll concentration output from a Yosemitech Y514-A chlorophyll sensor with wiper.
class YosemitechY514_Temp
The Variable sub-class used for the temperature output from a Yosemitech Y514-A chlorophyll sensor with wiper.

Defines

#define Y514_NUM_VARIABLES = 2
Sensor::_numReturnedValues; the Y514 can report 2 values.

Sensor Timing

The sensor timing for a Yosemitch Y514

#define Y514_WARM_UP_TIME_MS = 1300
Sensor::_warmUpTime_ms; time before sensor responds after power - 1.3 seconds (1300ms).
#define Y514_STABILIZATION_TIME_MS = 8000
Sensor::_stabilizationTime_ms; time between "StartMeasurement" command and stable reading - 8sec (8000ms).
#define Y514_MEASUREMENT_TIME_MS = 2000
Sensor::_measurementTime_ms; the Y514 takes ~2000ms to complete a measurement.

Chlorophyll Concentration

The chlorophyll concentration variable from a Yosemitch Y514

  • Range is 0 to 400 µg/L or 0 to 100 RFU
  • Accuracy is ± 1 %

YosemitechY514_Chlorophyll(YosemitechY514* parentSense, const char* uuid = "", const char* varCode = Y514_CHLORO_DEFAULT_CODE) explicit

Construct a new YosemitechY514_Chlorophyll object.

Parameters
parentSense The parent YosemitechY514 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 "Y514Chloro".

#define Y514_CHLORO_RESOLUTION = 1
Decimals places in string representation; chlorophyll concentration should have 1 - resolution is 0.1 µg/L / 0.1 RFU.
#define Y514_CHLORO_VAR_NUM = 0
Sensor variable number; chlorophyll concentration is stored in sensorValues[0].
#define Y514_CHLORO_VAR_NAME = "chlorophyllFluorescence"
Variable name in ODM2 controlled vocabulary; "chlorophyllFluorescence".
#define Y514_CHLORO_UNIT_NAME = "microgramPerLiter"
Variable unit name in ODM2 controlled vocabulary; "microgramPerLiter" (µg/L)
#define Y514_CHLORO_DEFAULT_CODE = "Y514Chloro"
Default variable short code; "Y514Chloro".

Temperature

The temperature variable from a Yosemitch Y514

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

YosemitechY514_Temp(YosemitechY514* parentSense, const char* uuid = "", const char* varCode = Y514_TEMP_DEFAULT_CODE) explicit

Construct a new YosemitechY514_Temp object.

Parameters
parentSense The parent YosemitechY514 providing the result values.
