Im going to build a CHEAP wifi, one that actually connects to the internet(not bluetooth! could easily convert to a 3G board but data costs 1.99/month ) multiple probe thermometer that uses up to ~6 thermocouples and arduino.
Without further adoo, heres what I got so far for prices:
Arduino wifi board $20
arduino to thermocouple board $8/piece
thermocouple $2.93 from china
power cord (usb) $3.00
box to hold it <$5.00
programming so you can see the temps/alerts phone anywhere your
phone is connected to the internet thru wifi or 3g-free! thats gonna be the fun part.
Total for 2 probes : ~$50 bux.
Anybody try this yet? I see a few arduino threads, but not really much to them as far as i can tell
Anybody have any ideas for things i may need to do or change? Is there anything like this on the market for this price range?
Would 2-5C be accurate enough (thats about the limit with cheaper thermocouples) otherwise I would have to use thermistors
and put them into a probe.. or just buy maverick probes for ~$10 which would make the total around ~$65-70.
