PROBLEMS IN READING CO2 SIGNAL #7

Closed rcanha closed 8 months ago

rcanha commented 8 months ago

We have a problem when executing the first example in the library: while the sensor is in start-up mode (2) the CO2 and total organic compounds values are displayed, but after a few minutes of operation the sensor status changes to standard (0) and the system displays readings equal to zero and stops working. I believe this is a problem in the library and I would appreciate it if you would change something so that CO2 measurements can be taken. Additionally, when I run the seventh program in the library, for a few minutes only the value 32767 is displayed and suddenly the value 1 is displayed and the program no longer displays anything.

Thanks for the issue. There's a lot I don't know about your setup. I have run the sensor as long as 8 hours without any issues, and this library has been around for over two years so I'm reluctant to say that "this is a problem in the library".

Can you give more information?

Thanks for your response. I'm using an ENS160+AHT2X sensor purchased on aliexpress. As I told you, using the library's example 1 program, readings stop after a few minutes. I faced the same problem in my custom program using "SparkFun_ENS160.h" for ens and using the "Adafruit_AHTX0.h" library for ahtx. Interestingly, even after stopping the display of CO2 and volatile organic readings, the AHT2 relative humidity and temperature readings continue normally. Thanks for your help.

According to the top comment on this thread, it looks like people have had success using this library in combination with our SparkFun_Qwiic_Humidity_AHT20_Arduino_Library with your particular board from Aliexpress.

Your issue is a bit out of the scope of a Github issue. If you find something wrong with the library please feel free to come back and reopen this issue.

Happy hacking!

The problem is not in the library for the AHT20 as the humidity and temperature data does not stop being displayed. The problem is with the EN160 library because CO2 and volatile organic data is only displayed while the sensor status is in Warm up. After reaching Standard status, only data from the AHT20 sensor is displayed.
