Sensor Constructor

Example Code

The Yosemitech Y533 ORP sensor is used in the menu a la carte example.

#include <sensors/YosemitechY533.h>

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

// NOTE: Use -1 for any pins that don't apply or aren't being used.
byte          y533ModbusAddress  = 0x32;  // The modbus address of the Y533
const int8_t  y533AdapterPower   = sensorPowerPin;  // RS485 adapter power pin
const int8_t  y533SensorPower    = A3;              // Sensor power pin
const int8_t  y533EnablePin      = 4;               // Adapter RE/DE pin
const uint8_t y533NumberReadings = 1;
// The manufacturer actually doesn't mention averaging for this one

// Create a Yosemitech Y533 ORP sensor object
YosemitechY533 y533(y533ModbusAddress, modbusSerial, y533AdapterPower,
                    y533SensorPower, y533EnablePin, y533NumberReadings);

// Create ORP and temperature variable pointers for the Y533
Variable* y533ORP =
    new YosemitechY533_ORP(&y533, "12345678-abcd-1234-ef00-1234567890ab");
Variable* y533Temp =
    new YosemitechY533_Temp(&y533, "12345678-abcd-1234-ef00-1234567890ab");

Classes

class YosemitechY533

The Sensor sub-class for the Yosemitech Y533 ORP sensor.

class YosemitechY533_ORP

The Variable sub-class used for the pH output from a Yosemitech Y533 ORP sensor.

class YosemitechY533_Temp

The Variable sub-class used for the temperature output from a Yosemitech Y533 ORP sensor.

Defines

#define Y533_NUM_VARIABLES = 2

Sensor::_numReturnedValues; the Y533 can report 2 values.

#define Y533_INC_CALC_VARIABLES = 0

Sensor::_incCalcValues; we don't calculate any additional values.

Sensor Timing

The sensor timing for a Yosemitch Y533

#define Y533_WARM_UP_TIME_MS = 500

Sensor::_warmUpTime_ms; time before sensor responds after power - 500ms.

#define Y533_STABILIZATION_TIME_MS = 4500

Sensor::_stabilizationTime_ms; time between "StartMeasurement" command and stable reading - 4.5sec (4500ms).

#define Y533_MEASUREMENT_TIME_MS = 1800

Sensor::_measurementTime_ms; the Y533 takes ~1800ms to complete a measurement.

pH

The ORP variable from a Yosemitch Y533

• Range is -999 to 999 mV
• Accuracy is ±20 mV
• Resolution is 1 mV

#define Y533_ORP_RESOLUTION = 0

Decimals places in string representation; ph should have 2 - resolution is 1 mV units.

#define Y533_ORP_VAR_NUM = 0

Sensor variable number; ORP is stored in sensorValues[0].

#define Y533_ORP_VAR_NAME = "voltage"

Variable name in ODM2 controlled vocabulary; "voltage" NOTE: ORP should be added to ODM2 CVs, as ORP refers to a specific measure of electron potential relative to a silver chloride reference electrode.

#define Y533_ORP_UNIT_NAME = "millivolt"

Variable unit name in ODM2 controlled vocabulary; "millivolt" (mV)

#define Y533_ORP_DEFAULT_CODE = "Y533ORP"

Default variable short code; "Y533ORP".

Temperature

The temperature variable from a Yosemitch Y533

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

#define Y533_TEMP_RESOLUTION = 1

Decimals places in string representation; temperature should have 1 - resolution is 0.1°C.

#define Y533_TEMP_VAR_NUM = 1

Sensor variable number; temperature is stored in sensorValues[1].

#define Y533_TEMP_VAR_NAME = "temperature"

Variable name in ODM2 controlled vocabulary; "temperature".

#define Y533_TEMP_UNIT_NAME = "degreeCelsius"

Variable unit name in ODM2 controlled vocabulary; "degreeCelsius" (°C)

#define Y533_TEMP_DEFAULT_CODE = "Y533Temp"

Default variable short code; "Y533Temp".
