Yosemitech Y511 Wipered Turbidty Sensor module

Classes for the Yosemitech Y511 wipered turbidity sensor.

Sensor Datasheet

Sensor Constructor

YosemitechY511(byte modbusAddress, Stream* stream, int8_t powerPin, int8_t powerPin2 = -1, int8_t enablePin = -1, uint8_t measurementsToAverage = 1)

Construct a new Yosemitech Y511 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 Y511. 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 Y511 wipered turbidity sensor is used in the menu a la carte example.

#include <sensors/YosemitechY511.h>

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

byte         y511ModbusAddress = 0x1A;  // The modbus address of the Y511
const int8_t y511AdapterPower  = sensorPowerPin;  // RS485 adapter power pin
                                                  // (-1 if unconnected)
const int8_t  y511SensorPower = A3;               // Sensor power pin
const int8_t  y511EnablePin   = -1;  // Adapter RE/DE pin (-1 if not applicable)
const uint8_t y511NumberReadings = 5;
// The manufacturer recommends averaging 10 readings, but we take 5 to minimize
// power consumption

// Create a Y511-A Turbidity sensor object
YosemitechY511 y511(y511ModbusAddress, modbusSerial, y511AdapterPower,
                    y511SensorPower, y511EnablePin, y511NumberReadings);

// Create turbidity and temperature variable pointers for the Y511
Variable* y511Turb =
    new YosemitechY511_Turbidity(&y511, "12345678-abcd-1234-ef00-1234567890ab");
Variable* y511Temp =
    new YosemitechY511_Temp(&y511, "12345678-abcd-1234-ef00-1234567890ab");

Classes

class YosemitechY511
The Sensor sub-class for the Yosemitech Y511-A optical turbidity sensor with wiper.
class YosemitechY511_Turbidity
The Variable sub-class used for the turbidity output from a Yosemitech Y511-A optical turbidity sensor with wiper.
class YosemitechY511_Temp
The Variable sub-class used for the temperature output from a Yosemitech Y511-A optical turbidity sensor with wiper.

Defines

#define Y511_NUM_VARIABLES = 2
Sensor::_numReturnedValues; the Y511 can report 2 values.
#define Y511_INC_CALC_VARIABLES = 0
Sensor::_incCalcValues; we don't calculate any additional values.

Sensor Timing

The sensor timing for a Yosemitch Y511

#define Y511_WARM_UP_TIME_MS = 8000
Sensor::_warmUpTime_ms; Y511 warms up in 8000ms.

500 ms to receive commands, but if activating brush warmup+stabilization must >20s

#define Y511_STABILIZATION_TIME_MS = 40000
Sensor::_stabilizationTime_ms; Y511 is stable after 40s.

warmup+stabilization > 48 s for consecutive readings to give different results

#define Y511_MEASUREMENT_TIME_MS = 4000
Sensor::_measurementTime_ms; Y511 take ~4s (4000ms) to complete a measurement.

Could potentially be lower with a longer stabilization time; more testing needed.

Turbidity

The turbidity variable from a Yosemitch Y511

  • Range is 0.1 to 1000 NTU
  • Accuracy is ± 5 % or 0.3 NTU

YosemitechY511_Turbidity(YosemitechY511* parentSense, const char* uuid = "", const char* varCode = Y511_TURB_DEFAULT_CODE) explicit

Construct a new YosemitechY511_Turbidity object.

Parameters
parentSense The parent YosemitechY511 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 "Y511Turbidity".

#define Y511_TURB_RESOLUTION = 2
Decimals places in string representation; turbidity should have 2 - resolution is 0.01 NTU.
#define Y511_TURB_VAR_NUM = 0
Sensor variable number; turbidity is stored in sensorValues[0].
#define Y511_TURB_VAR_NAME = "turbidity"
Variable name in ODM2 controlled vocabulary; "turbidity".
#define Y511_TURB_UNIT_NAME = "nephelometricTurbidityUnit"
Variable unit name in ODM2 controlled vocabulary; "nephelometricTurbidityUnit" (NTU)
#define Y511_TURB_DEFAULT_CODE = "Y511Turbidity"
Default variable short code; "Y511Turbidity".

Temperature

The temperature variable from a Yosemitch Y511

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

YosemitechY511_Temp(YosemitechY511* parentSense, const char* uuid = "", const char* varCode = Y511_TEMP_DEFAULT_CODE) explicit

Construct a new YosemitechY511_Temp object.

Parameters
parentSense The parent YosemitechY511 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 "Y511Temp".

Decimals places in string representation; temperature should have 1 - resolution is 0.1°C.
#define Y511_TEMP_VAR_NUM = 1
Sensor variable number; temperature is stored in sensorValues[1].
#define Y511_TEMP_VAR_NAME = "temperature"
Variable name in ODM2 controlled vocabulary; "temperature".
#define Y511_TEMP_UNIT_NAME = "degreeCelsius"
Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)
#define Y511_TEMP_DEFAULT_CODE = "Y511Temp"
