AnalogElecConductivity class

Class for the analog [Electrical Conductivity monitor](Conductivity via Analog Electrical Resistance)

Base classes

class Sensor: The "Sensor" class is used for all sensor-level operations - waking, sleeping, and taking measurements.

AnalogElecConductivity(int8_t powerPin, int8_t dataPin, float Rseries_ohms = 499, float sensorEC_Konst = 1.0, uint8_t measurementsToAverage = 1): Construct a new AnalogElecConductivity object.
~AnalogElecConductivity(): Destroy the AnalogElecConductivity object - no action needed.

String getSensorLocation(void) -> String override: Report the sensor info.
bool addSingleMeasurementResult(void) -> bool override: Get the results from a single measurement.
void setEC_k(float sourceResistance_ohms): Set EC constants for internal calculations. Needs to be set at startup if different from defaults.
float readEC(void) -> float: reads the calculated EC from an analog pin using the analog pin number set in the constructor.
float readEC(uint8_t analogPinNum) -> float: reads the calculated EC from an analog pin.

Construct a new AnalogElecConductivity object.

Parameters
powerPin	The port pin providing power to the EC probe. Needs to be switched, and assumed to be same V as the dataPin's ADC.
dataPin	The processor ADC port pin to read the voltage from the EC probe. Not all processor pins can be used as analog pins. Those usable as analog pins generally are numbered with an "A" in front of the number ie, A1.
Rseries_ohms	The resistance of the resistor series (R) in the line; optional with default value of 499.
sensorEC_Konst	The cell constant for the sensing circuit; optional with default value of 2.88 - which is what has been measured for a typical standard sized lamp-type plug.
measurementsToAverage	The number of measurements to average; optional with default value of 1.

Report the sensor info.

Returns	String Text describing how the sensor is attached to the mcu.

Get the results from a single measurement.

Returns	bool True if the function completed successfully.

This asks the sensor for a new result, verifies that it passes sanity range checks, and then adds the value to the result array.

Set EC constants for internal calculations. Needs to be set at startup if different from defaults.

Parameters
sourceResistance_ohms	series R used in calculations for EC

other possible K, not specified yet: float appliedV_V, uint8_t probeType

reads the calculated EC from an analog pin using the analog pin number set in the constructor.

Returns	float The electrical conductance value

reads the calculated EC from an analog pin.

Parameters
analogPinNum	Analog port pin number
Returns	float The electrical conductance value
