How to use DS18b20 with PID

Other Hardware Sensors
1

i have a ds18b20 temp sensor and a nice SSR to use for PID.

In the PID program it calls out an analog read of a pin for temp sensing.

Doesn't the DB18b20 have to operate on a digital pin? Is there a way to change the output from the temp sensor into a voltage for analogRead?

Will the PID program simply look at the input (from the sensor) as a dimensionless number simply to compare to the setpoint (99.5)?

Thanks,

Cam

Just use the temperature from the DS18B20 directly - no need to simulate an analog device.
