I´m writing asking for your help in order to know how to configure my temperature sensor.
I have just bought the temperature sensor model “DS18B20”, I have realized how to conect the sensor to get the readings (CELSIUS) due to some comments in the community.
But unfortunately the reading I have is -17.78 Celcius when the ambient temperatura is about 25º more or less.
It seems there is something wrong, maybe the only thing that I need to know in order to do the sensor works properly is how to calibrate it.
Please, could you help to close this issue?
Thanks so much for time!
