anyone use an ardunio much ?
the controller on my new (2nd hand) machine at work is dead
...and a new one will run into 4 figures... and it wasn't very easy to use anyway (it was a total pita)
so I'm thinking I could build an Arduino system instead
it's a drying machine for dog treats...
sensors/outputs are pretty easy
need to sense, air temperature going into the machine, inside the machine, and exiting the machine
and the humidity going in, inside, and coming out
start + stop buttons
outgoing controls are....
heaters (probably 2 outputs here for full/half heat)
inside fan
exhaust fan (this is currently inverter controlled, could still use the inverter?)
refrigeration compressor
simple screen output, to show what's going on....
time it's been running, the 3 temperatures, and also maybe something to show you which relays are powered up
everything inside the machine is already powered up via low voltage relays, so that's not a problem
(tho might still need something to power these between them and the arduino)
anyone know how easy/reliable this would be to do before I buy the gear ?
I did programming at A level and for my degree so I'm happy with that
I was thinking of using these as sensors...
http://proto-pic.co.uk/hih-4030-humidity-sensor-breakout/anyone know if they'll be ok up to high temp ? I shouldn't need to go past 100'C but it would be better to built something to take 200'C just incase...
these temp sensors look good too... nice high temps, but no humidity :-(
http://proto-pic.co.uk/thermocouple-type-k-glass-braid-insulated/can I use another off the shelf humidity sensor instead ? (one better matched to the high temps)
