The SIP class constructs objects that represent a single "SiP" or "System-In-Package" module (eg. IMU, MEMS) attached to the physical board. An SiP may be made up of several components like Accelerometers, Gyroscopes, Thermometers, and Compass/Magnetometers.

  • SparkFun
  • Grove
• BMP280

Parameters

• General Options

  Property	Type	Value/Description	Default	Required
  controller	string	BMP180, BMP280, BME280, HTU21D, HIH6130, MPL115A2, MPL3115A2, SI7020, SI7021, MS5611, TH02. The Name of the controller to use		yes
  freq	Number	In milliseconds, how often data events should fire	20	no

In addition, anything in the options object passed to the SIP constructor will be passed along to each of its constituent component sensors (e.g. Thermometer, Altimeter, etc.). See relevant sensor component class documentation for more details about what options each takes.

API

The SIP class does not have an explicit API. Refer to the individual components for their APIs

Events

• data The "data" event is fired as frequently as new data becomes available.

• change The "change" event is fired whenever a corresponding "change" is fired from any constituent component.

Note: You may also bind to events on SIP object component sensors directly, e.g. sip.thermometer.on('change')
