https://greenshoegarage.com/2020/10/learning-from-covid-19/

Goal

An open-source device that can monitor 8+ key environmental factors that affect people's perception of a healthy and productive workspace:

  • Temperature

  • Pressure

  • eCO2

  • Humidity

  • Brightness

  • Noise

  • TVOC

  • PM 2.5um

Code and hardware is a prototype, no guarentee of any sort is implied. Use at your own risk.

Functionality
