|

// Summary: PS_AdafruitVEML7700_Illuminance is a class which implements the SmartThings "Illuminance Measurement" device capability.
|
||||
// It inherits from the st::PollingSensor class. It uses I2C communication to measure the Illuminace from a VEML7700 sensor.
|
||||
//
|
||||
// Create an instance of this class in your sketch's global variable section
|
||||
// For Example: st::PS_AdafruitVEML7700_Illuminance sensor1(F("illuminance1"), 60, 0); (simple, uses defaults)
|
||||
// For Example: st::PS_AdafruitVEML7700_Illuminance sensor1(F("illuminance1"), 60, 0, VEML7700_IT_50MS, VEML7700_GAIN_1_8); (full user control of settings)
|
||||
//
|
||||
// st::PS_AdafruitVEML7700_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
|
||||
// - uint8_t integrationTime - OPTIONAL - defaults to VEML7700_IT_50MS
|
||||
// - uint8_t gain - OPTIONAL - defaults to VEML7700_GAIN_1_8
