We have been researching COVID-19, and it’s virality within building-space based on particulate matter and humidity levels. Within different research, the outcome of the results is particulate matter, and humidity has profound effects on how the virus spreads.
We have been working on a project within project SandStar, which was called an indoor air quality sensor. We are open sourcing everything within this project for hospitals and other spaces to monitor indoor air quality to mitigate the spread of infections in the future.
I would like to thank Marwa Zaatari for posting most of this research in which it let us open source what we have generated.
ANALYSIS – PARTICULATE MATTER
The first research is from Italy on the effects of particulate matter and the quantity of virality. The image below will summarize the impact that they have found. We have attached the article itself as well.
Figure 1: Correlation infected persons -PM10exceedances.
Figure 2: Mean of PM10 exceedances/number of monitoring stations in selected Italian Provinces in the period 10th-29th February 2020.
ANALYSIS – HUMIDITY & TEMPERATURE
According to the research from Chapel Hill, North Carolina impact curve for relative humidity on respiratory viruses is parabolic. The outcome of the research means; humidity control with high precision will be a crucial factor in controls.
This will require many devices to keep track of humidity levels and correct behavior of the control systems.
ANALYSIS – VIRALITY
Here are two other articles that has lead us to the decision to open-source to project.

PROJECT SANDSTAR IAQ
This project consists of four different sections.
Code
The first section is the integration of project SandStar into AM 4100 and indoor air quality sensor.
The application converts the UART protocol and exposes all the data to Project Haystack Project utilizing project sandstar.
Technology Used
We have merged two technologies into one and named it Project Sandstar.
Electronics Board Design
The second part is electronic design for BeagleBone, where we have created a hat and a lighting panel.
Industrial Design
The third section is the industrial design, where we have created an inside plastic area to hold the electronics ports as well as plastic that we had picked where the inside plastic molding will be placed in.
Analytics Engine
Analytics engine that is clusterable between devices so that we can do analytics results over historical data time. This section can be enhanced to be able to used by cloud connections with haystack. Basically, anyone can get the data from the haystack and merge it into their analytics engine.
HOW DOES
IT WORK?
Concept is utilizing Sandstar with reading data from UART and passing the data to haystack. From here, anyone can read this data to their own cloud or integrate it with SkySpark. You can choose to fund the project further buying points from us. All design is open including plastic step files for inboard design.
