Unreliable air quality sensor

I bought two of these and i installed into two radios. I have ran the following test in 3 locations: outside, living room, basement

I left them overnight to acclimate, both radios open air side by side

After 12 hours one night give a reading of 35 and the other 95, every time the air quality readings are very far apart

The other 3 sensors are always in agreement within a percent or two: temp, humidity, pressure

If buying for the air quality data, i can't recommend it. The other 3 data points seem fine

Environment sensor

Works really nicely. Quick to populate the initial readings and appears to be accurate.

Great Environmental Sensor

The RAK1906 is a great use of the Bosch BME680 chip and provides temperature, humidity, and atmospheric pressure which can be displayed on the RAK 0.96" OLED Display.

I do wish that the atmospheric pressure readout was adjustable to different formats, and above all, I wish that I could figure out how to transmit the environmental data as a text message to other Meshtastic in my mesh.

This Covers all Environments

I have these installed in all of my outdoor WisBlock builds. For me, it's a benefit to keep track of environmental data in particular locations. It's a bit pricey, however, it's accurate and has very low power consumption which allows for small single battery / small solar panel builds.
