I’m Dario from Bochum, Germany and today i started to use an Arduino Nano V3 with the osPID Firmware to get a Sous-Vide controller.
As I had none of the supported sensors but some waterproof DS18B20 Sensors http://bit.ly/DS18B20Waterproof
I decided to implement the One-Wire Sensors in the firmware.
Due to the very good documented source code it was easy to add the OneWire-Lib.
If anyone is interested, i can provide the changes I made.
But now I have two questions:
1) What is the right way to tune the PID Parameters?
2) Is there e posibility of long-time recording the parameters? The Gui shows 5 minutes, Sous-Vide is an 8 hour process.
