Question about an error-massage

[MusiMaster]

Hi all,

i was trying to measure the co2-ppm with the help of your guide.

i did:

- pip install mh-z19

and then:

-sudo python

>>> import mh_z19

>>> mh_z19.read()

after that nothing happens until i press CRTL+C end get this error-massage:

>>>mh_z19.read()

^CTraceback (most recent call last):
  File "/usr/local/lib/python3.9/dist-packages/mh_z19/__init__.py", line 69, in mh_z19
    result=ser.write(b"\xff\x01\x86\x00\x00\x00\x00\x00\x79")
  File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 622, in write
    abort, ready, _ = select.select([self.pipe_abort_write_r], [self.fd], [], None)
KeyboardInterrupt
{}
>>>

my python-version is:

Python 3.9.2 (default, Mar 12 2021, 04:06:34)
[GCC 10.2.1 20210110] on linux
