// Authors: Dan G Ogorchock & Daniel J Ogorchock (Father and Son)
//
// Summary: PS_Illuminance is a class which implements the SmartThings "Illuminance Measurement" device capability.
// It inherits from the st::PollingSensor class. The current version uses an analog input to measure the
// value of a simple photo resistor.
//
// 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 (0 to 1024) to Lux before sending to SmartThings. The
// defaults for this sensor are based on the device used during testing.
//
// Create an instance of this class in your sketch's global variable section
// For Example: st::PS_Illuminance sensor1(F("illuminance1"), 120, 0, PIN_ILLUMINANCE, 0, 1023, 0, 1000);
//
// st::PS_Illuminance() 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 a digital output
// - int s_l - OPTIONAL - first argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output
// - int s_h - OPTIONAL - second argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output
// - int m_l - OPTIONAL - third argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output
// - int m_h - OPTIONAL - fourth argument of Arduino map(s_l,s_h,m_l,m_h) function to scale the output
//
// 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
