Attitude sensor

[macjl]

Hello,

Do you think the Ruuvi acceleration sensors could be used to provide attitude (yaw, pitch, roll) informations to signalk ?

[macjl]

I created a "signalk-derived-data" calculation that may work. maybe this could be integrated directly in this plugin ?

module.exports = function (app, plugin) {
  return {
    group: 'heading',
    optionKey: 'attitude',
    title:
      'Attitude Yall, Pitch (based on environment.inside.mainCabin.acceleration[X,Y,Z])',
    properties: {
      correctRoll: {
        type: 'number',
        title: 'Correction of roll',
        default: 0
      },
      correctPitch: {
        type: 'number',
        title: 'Correction of Pitch',
        default: 0
      }
    },
    derivedFrom: [
      'environment.inside.mainCabin.accelerationX',
      'environment.inside.mainCabin.accelerationY',
      'environment.inside.mainCabin.accelerationZ'
    ],
    calculator: function (accelerationX, accelerationY, accelerationZ) {
        var correctPitch = plugin.properties.heading.correctPitch
        var correctRoll  = plugin.properties.heading.correctRoll
        var pitch = correctPitch / 57.29578 + Math.asin( accelerationX / Math.sqrt( accelerationX^2 + accelerationY^2 + accelerationZ^2 ))
        var roll  = correctRoll  / 57.29578 + Math.asin( accelerationY / Math.sqrt( accelerationX^2 + accelerationY^2 + accelerationZ^2 ))
      return [
        {
          path: 'navigation.attitude',
          value: {
                pitch: pitch,
                roll: roll
                }
        }
      ]
    }
  }
}
