Wind & Weather 2x3 Display

This is a marine wind & weather display which is made for waterborne vessels. This version only works for 2x3 monitors .

This microcontroller displays apparent & true wind speeds and directions along with the time, temperature, fog & rain info. It also shows your vehicle's heading & has a compass on the screen to show your bearings and the wind's bearings.



Example on my hovercraft





Apparent wind is the wind felt from your vehicle's motion combined with the true wind . In other words, it's the raw values you would get from your vehicle's wind sensor.

Apparent wind is partially affected by your vector and speed.





True wind is the wind felt as if you are standing still . The microcontroller is able to accurately calculate the true wind speed and direction in real-time even when your vehicle is moving, reversing, turning, drifting etc.

True wind is not affected by your vector and speed.

• Accurately displays wind speeds and directions in real-time even when moving
  
• Displays the bearings of true and apparent wind while also displaying their angles relative to your vehicle (via the lines in the circle)
  
• Displays time, temperature, fog & rain info & vehicle heading
  
• Compass display
  
• Selectable measurement units (for wind speeds and temperature)

Heading (HDG) - Heading of your vehicle
True Wind Angle (White Line) - Angle of where the true wind is coming from relative to your vehicle
Apparent Wind Angle (Blue Line) - Angle of where the apparent wind is coming from relative to your vehicle
True Wind Bearing (TWB) - Bearing of where the true wind is coming from relative to north
Apparent Wind Bearing (AWB) - Bearing of where the apparent wind is coming from relative to north
True Wind Speed (TWS) - Speed of true wind
Apparent Wind Speed (AWS) - Speed of apparent wind
Time - 24-hour clock
Ambient Temperature (Temp) - Temperature of surroundings
Rain - Chance of rain
Fog - Fog thickness

Wind directions show “Nil '' when the wind is not strong enough (less than 3 knots) as it's not possible to have wind direction if there is no wind.




I recommend you copy & paste the components together with the microcontroller onto your vehicle then using the cut & paste tool to move them around in order to avoid incorrect sensor placements but if you decide to place the sensors on your own:

The components which are to be connected with the nodes are listed on each microcontroller node.

Ensure that:

• the compass sensor is placed upright facing forward of the vehicle.
  
• the “Absolute Speed Sensor” mode is set to “Absolute”
  
• the forward “Linear Speed Sensor” is placed facing forwards and is set to “directional” mode
  
• the right “Linear Speed Sensor” is placed facing the right and is set to “directional” mode
  
• the GPS sensor has electrical power
  
• temperature probe is not placed near heaters (if possible)

[Do not use mirror for any of the sensors!]






Wind Speed Unit - Unit used to display wind speeds (knots, m/s, kph, fps, mph)
Max Radar Range - Unit used to display ambient temperature (°C, °F)





Thank you for taking the time to read through the description.

As mentioned earlier, this microcontroller only works for 2x3 screens but I might make separate versions for different screen sizes in the future. (no promises)

Slight deviations of the true wind direction and speed values are expected (especially when performing rough movements with your vehicle). This is because many variables are in play to calculate true wind values.

You are free to use this microcontroller on your vehicles but please credit me by providing a link to this page if you upload your vehicle to the workshop with my creation. Please do not reupload my creation/modified versions onto the workshop.

Please report any bugs or issues you find and any feedback is welcome. I would also appreciate it if you leave a rating/favourite if you find this wind & weather display useful.
