This analog gauge scale fits the top plate of the ProtoStax Micro Servo Analog Gauge Add-On, and provides a scale for Air Quality Index, going from 0-50 (green), 51-100 (yellow), 101-150 (orange), 151-200(red), 201-300 (purple), and a little maroon for > 301! 

It is made of card-stock paper and has cutouts for a micro-servo and RGB LED, as well as for the mounting holes, so you can attach this to the top plate of your ProtoStax Micro Servo Analog Gauge Add-On and screw them both into your ProtoStax Enclosure. 

Now you can display the Air Quality Index reading as a retro analog gauge using a micro-servo (along with ProtoStax Analog Gauge Needle Horn for Micro Servo - 2F 21 Teeth to be used as the needle (or make and use your own!))

ProtoStax Enclosures are Stackable, Modular & Extensible

They ease your path from Prototype to Product! Make your prototypes useable and attractive with ProtoStax!

  • ProtoStax Enclosure / Case in Platform Configuration showing Arduino. Pre-drilled and threaded mounting holes make assembly easy and convenient. Acrylic risers elevate board off the surface for improved airflow

    Use it as a prototyping plate, with full and open access to your device while prototyping. Rubber feet protect your board and your table top! 

  • ProtoStax Enclosure / Case in Open Configuration showing Arduino

    Omit the side walls and just add the top for an open configuration with more airflow and open access. 

  • ProtoStax Enclosure / Case in Fully Closed Configuration showing Arduino

    Add side walls and the top to form a fully enclosed case for maximum protection. 

    The cases offer connectivity to external systems using our unique cable management methods (see features above)


Extension kits and Add-Ons allow you to add functionality to your enclosure. Add a fan or two, switches, camera & tripod mount, and more!

Just filter by "extension kit" or "add-on" in the main shopping page to view the choices, or click below!

All ProtoStax cases are compatible with each other and can be stacked side-by-side (horizontally) or one on top of the other (vertically). Mix-and-match multiple ProtoStax cases and put together a larger enclosure from the individual ones! Our Raspberry Pi + Breadboard, or Raspberry Pi + Arduino enclosures are popular bundles. You can also mix-and-match various Raspberry Pi enclosures (A+, B/B+, Zero enclosures to build your hybrid cluster with whatever Pis you have lying around!)
