hi guys
this is my quickly made up controller using bits from the deepest darkest recesses of my shed and some cheap stuff i needed from ebay(£12 controller,£3 switches,£1.50 fan) the controller is 12 volt and came from china it was supplied with a k type thermocouple, the food storage box was raided from the kitchen (she was not pleased) i have not bothered to use a solid state relay yet but i may include one on the next version and also incorporate an alarm into the system
the tiny pid controller fitted next to the 2 switches (top) on/off(bottom) is fan disable. the box was very brittle to cut and kept snapping bits off and i cracked it quite badly hence the sticky tape. the fan switch is to turn off the fan when i lift the lid on the smoker and i will turn the fan back on again when the temperature is stable
k type thermocouple that was included with controller
12v cigarette lighter plug
a brass water tank fitting and a 3/4 inch flexi hose i have another brass fitting to go in the uds drum for the other end of the pipe to fit on to
powered up, it is a 80 mm fan and it is capable of moving 24 cfm but as i am making it push air down a 6ft long 3/4 inch pipe that amount is drastically reduced to approx 8 cfm and hopefully it will be about right for the uds
the controller manual listed settings for the P.I.D. that are suitable for use on smokers they are
P 1.2
I 300
D 70
hope that helps anyone setting up one for themselves
i will be giving it a trial run this week so fingers crossed it will work ok
