Workspace Health Monitoring Gadget

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

1. Monitor 8 environmental factors
   1. Central processing of all sensor data
2. Record the telemetry locally
   1. 24-hour rolling log
   2. Store on microSD card
3. Display the telemetry locally
   1. Display new data point every 3 seconds
4. Transmit telemetry to web-based cloud service
   1. Send latest sensor readings every 10 minutes
