|
|
// Summary: PS_BH1750_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 MAX44009 sensor.
|
||
|
|
//
|
||
|
|
// Create an instance of this class in your sketch's global variable section
|
||
|
|
// For Example: st::PS_BH1750_Illuminance sensor1(F("illuminance1"), 60, 0); (simple, uses defaults)
|
||
|
|
// For Example: st::PS_BH1750_Illuminance sensor1(F("illuminance1"), 60, 0, BH1750_ADDR_LOW); (full user control of settings)
|
||
|
|
//
|
||
|
|
// st::PS_BH1750_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 addr -OPTIONAL - defaults to BH1750_ADDR_LOW
|
||
|
|
//
|
||
|
|
//
|
||
|
|
// I2C address options
|
||
|
|
// BH1750_ADDR_LOW 0x23 //< Pin A0 pulled Low
|
||
|
|
// BH1750_ADDR_HIGH 0x5C //< Pin A0 pulled Hi
|
||

|
||
|
|
// 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.
