Dear All,
I am a Beginner of Arduino.
I have a project for control temperature for three zones.
I know I can use PWM function for control SSR, and I will try to learn how to develop PID function.
But now, I would like to know how to use the DS18B20 sensor library.
I know Arduino have a library for this sensor and canbe connect many sensors together.
I have two queastions:
-
Because all sensor are connected in parallel, How can I know which one will assign for 0? Is this will be change after next power on?
-
If one of sensor out of order after long time working, is this will change the order number of other old sensors after I changed new sensor?
Thank you!
