// File: PS_Water.h
// Authors: Dan G Ogorchock & Daniel J Ogorchock (Father and Son)
//
// Summary: PS_Water is a class which implements both the SmartThings "Water Sensor" device capability.
// It inherits from the st::PollingSensor class. The current version uses an analog input to measure the
// presence of water using an inexpensive water sensor.
//
// Create an instance of this class in your sketch's global variable section
// For Example: st::PS_Water sensor3(F("water1"), 60, 6, PIN_WATER, 200, false);
//
// st::PS_Water() 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
// - int limit - OPTIONAL - the alarm limit to compare analog pin's reading to, above which the sensor reports "wet" instead of "dry", default = 100
// - bool invertLogic - OPTIONAL - if set to true, will invert the comparison against target from < to >, default = false
//
// 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
//
// Change History:
//
// Date Who What
// ---- --- ----
// 2015-01-03 Dan & Daniel Original Creation
// 2015-08-23 Dan Added optional alarm limit to constructor
// 2018-10-17 Dan Added invertLogic parameter to constructor
