//
//  Summary:  PS_AdafruitAM2320_TempHumid is a class which implements the "Temperature Measurement"  
//			  and "Relative Humidity Measurement" device capabilities.
//			  It inherits from the st::PollingSensor class.  The current version uses I2C to measure the 
//			  temperature and humidity from an AM2320 series sensor using the Adafruit_AM2320 library.  
//
//			  Create an instance of this class in your sketch's global variable section
//			  For Example:  st::PS_AdafruitAM2320_TempHumid sensor2("AM2320_1", 60, 0, "temperature1", "humidity1", false, 100);
//
//			  st::PS_AdafruitAM2320_TempHumid() constructor requires the following arguments
//				- String &name - REQUIRED - the name of the object - must be unique, but is not used for data transfer for this device
//				- long interval - REQUIRED - the polling interval in seconds
//				- long offset - REQUIRED - the polling interval offset in seconds - used to prevent all polling sensors from executing at the same time
//				- String strTemp - REQUIRED - name of temperature sensor to send to ST Cloud (e.g."temperature1")
//				- String strHumid - REQUIRED - name of humidity sensor to send to ST Cloud (e.g. "humidity1")
//				- bool In_C - OPTIONAL - true = Report Celsius, false = Report Farenheit (Farentheit is the default)
//				- byte filterConstant - OPTIONAL - Value from 5% to 100% to determine how much filtering/averaging is performed 100 = none (default), 5 = maximum
//
//            Filtering/Averaging
//
//            Filtering the value sent to ST is performed per the following equation
//
//            filteredValue = (filterConstant/100 * currentValue) + ((1 - filterConstant/100) * filteredValue) 
//
//			  This class supports receiving configuration data from the SmartThings cloud via the ST App.  A user preference
//			  can be configured in your phone's ST App, and then the "Configure" tile will send the data for all sensors to 
//			  the ST Shield.  For PollingSensors, this data is handled in the beSMart() function.
//
//			  TODO:  Determine a method to persist the ST Cloud's Polling Interval data
//
