DS18B20 error

[Roberthh]

What I understand: While the above script is running, you disconnect the sensor.

In that case, the read function will read invalid data, obviously with a wrong CRC, and raises a CRC error. That is the expected behavior.
In your script you can catch the CRC error with try/except clause around read.temp(), e.g. as:

Code: Select all

    for rom in roms:
    	try:
            print (ds.read_temp (rom), end = '|')
       except CRCError:
           print("CRC error reading the termperature, unit", rom)

In that case, the script will continue and print error message until you reconnect the sensor.
Obviously, you may implement any reasonable error handling instead.

You need the 750ms delay placed directly after the ds.convert_temp().
