Good afternoon
I've stop used the temperature sensor, since I have conflicts to other probes...
To read well the LM35DZ I have to use 'analogReference(INTERNAL1V1)'... ok...
But when I try to read other probes... PH, ORP.... I need 5V... than I use analogReference(DEFAULT)...
Literature says that on 1st reading, after changing analogReference, will have some strange values... but it seems is that the wrong values remains forever...
What do you suggest?
Thanks on advance
Best regards
