I'm hoping to build off previous posts about volatile organic compound (VOC) sensors (here about the CCS811 sensor, and here about PID sensors), and synthesize information on low-cost VOC sensors for the current research area review on outdoor air quality.
What are people's experiences using low-cost VOC sensors outdoors?
A couple of air quality researchers I've talked to say that currently available low-cost metal oxide (MOX) and photoionization detector (PID) sensors don't produce accurate data.
A few related questions:
- What can cause these VOC sensors to produce inaccurate data?
- What can/do people use these low-cost VOC sensors for? E.g., initial investigations into relative total VOCs, etc.
- What's needed to improve the accuracy of low-cost VOC sensor data? E.g., hardware improvements, calibrations/corrections, etc.?
Thanks for any insights folx can share!
@cfastie @sarasage The conversation you had in the comments of this post mentioned above was very helpful. Do you happen to have any updates from the field or thoughts on the questions above re: accuracy of lower-cost VOC sensors outdoors?
@robert_winkler Would you be able to share insights from MeteoMex?
Thanks to all for any thoughts, experiences, or words of wisdom you can share.
