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
