// File: PS_SoundPressureLevel.h
// Authors: Dan G Ogorchock & Daniel J Ogorchock (Father and Son)
//
// Summary: PS_SoundPressureLevel is a class which implements the "Sound Pressure Level" device capability.
// It inherits from the st::PollingSensor class. The current version uses an analog input to measure the
// voltage on an anlog input pin and then scale it to engineering units.
//
// The last four arguments of the constructor are used as arguments to an Arduino map() function which
// is used to scale the analog input readings (e.g. 0 to 1024) to Engineering Units before sending to SmartThings.
//
// Create an instance of this class in your sketch's global variable section
// For Example: static st::PS_SoundPressureLevel sensor1(F("soundPressureLevel1"), 60, 0, PIN_SPL, 0, 1024, 0.0, 165.0, 50);
//
// st::PS_SoundPressureLevel() constructor requires the following arguments
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
// - 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
// - byte pin - REQUIRED - the Arduino Pin to be used as an analog input
// - double s_l - OPTIONAL - first argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output - minimum raw AI value
// - double s_h - OPTIONAL - second argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output - maximum raw AI value
// - double m_l - OPTIONAL - third argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output - Engineering Unit Min (or Max if inverting)
// - double m_h - OPTIONAL - fourth argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output - Engineering Unit Max (or Min if inverting)
// - long m_nHighSpeedPollingInterval - OPTIONAL - number of milliseconds between high speed analog reads - defaults to 50ms
//
// 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
