Constructor Details

#initialize(opts = {}) ⇒ Configuration

Initializes sensors

Parameters:

  • opts (Hash) (defaults to: {}) —

    sensors’ configuration

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

Invokes event for any sensor

Raises:

  • (ArgumentError) —

    unless sensor exists
