Turning an S8 ABC off

[JarredAwesome]

Hey everyone,

I just bought my S8, and am eagerly awaiting it’s arrival.

I have found that there are not a lot of good python Libraries for it.

I want to turn off it’s ABC because it’s going in a very high co2 environment.

I found one library that has a command just called ‘s8_abc’. It doesn’t say if it’s to turn it on, off, set a baseline... anything.

The code it sends to the sensor is: \xfe\x03\x00\x1f\x00\x01\xa1\xc3

Anyone know what this is for?

We're not officially allowing for turning it off. But it's easy to do in the official application from SenseAir. https://senseair.com/media/2001/uip5_0_0_3_40_setup.exe

The reason is that it have done more harm than good when it's too easy to do. But if you know why you're turning it off then the extra step to do it with their UIP5 shouldn't be too much.

My sensor will be sitting in an environment that is constantly over 5000 ppm. So I feel the abc won’t be a good thing to have on.

I only have a Mac, is there a Linux or max port for that?

Will powering down the sensor once a day prevent it from auto calibrating?

I don't know, but the 1 day interval is not the default interval of the S8.
That's the interval for the MH-Z19 sensors.

The S8 abc period is 15 days. So I guess my real question is:
If I interrupt the power within the time, will it prevent it from doing abc?

I don't know.

I wrote to Sensair directly.

They sent me this

Thanks everyone
