|
||
|
|
// Summary: PS_AdafruitThermocouple is a class which implements the SmartThings "Temperature Measurement"
|
||
|
|
// device capability.
|
||
|
|
// It inherits from the st::PollingSensor class. The current version uses a digital input to measure the
|
||
|
|
// temperature Adafruit MAX31855 series thermocouple sensor.
|
||
|
|
//
|
||
|
|
// Create an instance of this class in your sketch's global variable section
|
||
|
|
// For Example: st::PS_AdafruitThermocouple sensor1(F("temperature1"), 120, 3, PIN_SCLK, PIN_CS, PIN_MISO);
|
||
|
|
//
|
||
|
|
// st::PS_TemperatureHumidity() 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
|
||
|
|
// - int8_t pinSCLK - REQUIRED - the Arduino Pin to be used as the MAX31855 SCLK
|
||
|
|
// - int8_t pinCS - REQUIRED - the Arduino Pin to be used as the MAX31855 CS
|
||
|
|
// - int8_t pinMISO - REQUIRED - the Arduino Pin to be used as the MAX31855 MISO
|
||
|
|
//
|
||
|
|
// 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.
