These BME688 sensors in these newer units are only accurate to 0.5 degrees Celsius or 0.9 degrees Fahrenheit. Likewise, other sensors on the market have a bit more accuracy (down to 0.1-degree Fahrenheit in senors for Arduino). In fact, AQI is a function that incorporates the biggest element in a set of elements:
- ground-level ozone
- particle pollution (also known as particulate matter, including PM2.5 and PM10)
- carbon monoxide
- sulfur dioxide
- nitrogen dioxide
The BME688 does do VOCs in aggregate, but can you accurately split them out? Even Bosch says this is experimental.
I know the most pressing issue with this device was price and that is fair.
This is composed of some sort of Arduino board (of a variant)?
Are there any spec sheets on the whole sensor? It’s made by and from many sources I see; but an overall schematic?
How is AI working in the background to normalize all these values?
Any need for beta testers for future products and software?
Any way we could connect better sensors into or to this device?
