|

//
|
||||
// Summary: PS_DS18B20_Temperature is a class which implements both the SmartThings "Temperature Measurement" capability.
|
||||
// It inherits from the st::PollingSensor class. The current version uses a digital pin to measure the
|
||||
// temperature from a Dallas Semiconductor One Wire DS18B20 series sensor.
|
||||
//
|
||||
// Create an instance of this class in your sketch's global variable section
|
||||
// For Example: st::PS_DS18B20_Temperature sensor1(F("temperature1"), 120, 0, PIN_TEMPERATURE, false); (for a single sensor)
|
||||
// st::PS_DS18B20_Temperature sensor1(F("temperature"), 120, 0, PIN_TEMPERATURE, false, 10, 3); (for 3 sensors)
|
||||
//
|
||||
// st::PS_DS18B20_Temperature() constructor requires the following arguments
|
||||
// - String &name - REQUIRED - the name of the object - either "temperature1" for a single sensor, or "temperature" for multiple sensors
|
||||
// - 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 for the One-Wire DS18B20 sensor conenction
|
||||
// - bool In_C - OPTIONAL - true = Report Celsius, false = Report Farenheit (Farentheit is the default)
|
||||
// - byte resolution - OPTIONAL - DS18B20 sensor resolution in bits. 9, 10, 11, or 12. Defaults to 10 for decent accuracy and performance
|
||||
// - byte num_sensors - OPTIONAL - number of OneWire DS18B20 sensors attached to OneWire bus - Defaults to 1
|
||||
// - byte sensorStartingNum - OPTIONAL - Starting number for sending temperature sensor data when using multiple sensors on one pin - Defaults to 1
|
||||
//
|
||||
// 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

||||

// Date Who What

|

// 2015-10-08 Matt Boykin Original Creation

|
||||
// 2016-02-27 Dan Ogorchock Added support for multiple DS18B20 sensors
|
||||
// 2017-08-18 Dan Ogorchock Modified to send floating point values to SmartThings
|
||||
// 2018-08-30 Dan Ogorchock Modified comment section above to comply with new Parent/Child Device Handler requirements
|
||||
// 2019-03-11 Dan Ogorchock Added new optional parameter for starting sensor number for data transfer
|
||||
// 2019-07-05 Dan Ogorchock Fix bug in multiple sensor support logic
