Hi, I am working on a project to develop an integrated control system of coffee roaster, which can collect the following data:
 
drum speed
fan speed
Power
Bean temperature
Eviroment temperature
Heater temperature
Maximum environment temperature
Ambient temperature
Barometric pressure
Humidity
 
the system also has PID functions to roast according to one previous curve of the four temperatures listed above, User can also program his/her roast with the system based on time and/or events
 
I am wondering if I could request your effort to add the system to the software and what information you need.
And any advice will be well appreciated.
 
I am looking forward your early reply.
 
Allen
