ProtoStax Analog Gauge Scale for Air Quality Index
The product is out of stock
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!
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!
Omit the side walls and just add the top for an open configuration with more airflow and open access.
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)
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!)
