Oh no, not at all. I use the SKIPROM command here which assumes there is only one sensor on the OneWire bus. But, it seems like it would be pretty fun to extend this so it did what you are asking. Let me work on it tomorrow and I'll post something back later this weekend.

I think that is correct unless other Dallas temperature sensors have the same commands and output their results in the same way. What else were you hoping that it may support?

If an admin sees this would you please change the name of this thread to "DS18B20 - Now No Resistor Needed" and delete this post. Thanks!

It has been a very long time since I brewed or posted here but I just recently learned how to eliminate the need for 4.7kOhm resistors when using DS18B20 temperature sensors. Essentially we make some changes to a few OneWire routines to use the pull-up resistors in the microprocessor instead of...

FuzzeWuzze is correct. One pin on the Arduino Uno will support 5 DS18B20's no problem captrichc.

This definitely does not have full Ethernet library support. All it is doing at the moment is opening a socket to a server, sending data through that socket, and then closing the socket. I don't think it would be terribly difficult for me to add the ability to receiving data through the socket...

Xively feed from this code These charts might not be recording data at any given moment as I test new code Earlier this year I became interested in FuzzeWuzze's excellent guide to a Real Time Online Fermentation Temperature Monitor for ~$60 which I bought the parts for and implemented...

I'm pretty sure they came from Lowes though it might have been Home Despot.

I've done a ton of work with the DS18B20s on a OneWire network up to and including writing my own OneWire Code to save space on the microcontroller. My code is WAY less abstracted than trying to wade through the DallasTemperature and OneWire libraries too. Below is some code I wrote to quickly...

3/16" wide, sounds like there will not be very much end grain available for your beer. Based on what I've read that means it will take a very long time to get full interaction which is why the infusion spirals work so well. It is totally up to you, what you've bought will work given enough...

It is true that 5 gallons of water has quite a thermal mass. One has to either add or remove 43,966 Joules of energy to change the temperature of five gallons of water 1°F. So let's use the worst case scenario, fermentation is over and you want to cold crash your beer down to 40°F starting at...

I hear you on the not getting to do real engineering for a living! The only time I really get to use my training is for my various mad scientist hobbies. At least selling out pays well! My spreadsheet does take into account heat gain through all six surfaces. Again I do neglect the...

I don't know the dimensions of your inside box so I just assumed 24"x36" and 24" tall. With a thermal conductivity of the foam of 0.018 BTU/hr ft² °F ft and neglecting the insulative value of the plywood I come up with a heat flux of 30 watts with a temperature differential of 30°F. We don't...

I bought a pretty good amount from Rockler. How much are you looking for? I can dip into my personal stash if you don't want to fool with Rockler.

The OneWire protocol has been looking a little portly to me for a while now so I went one step further with it and rewrote all the read_bit, read, write_bit, write, and reset functions to twiddle ports directly rather than doing it through the #defines that OneWire uses. I removed a little of...

I came across Atmel AVR4027: Tips and Tricks to Optimize Your C Code for 8-bit AVR Microcontrollers and applied what I could to my fermentation monitor code to tremendous effect. As I speculated I was doing some things stupidly especially global variables which burn up SRAM big time! My newest...

Good to know that you've got at least some code for it. I found an EtherShield libraray which it seems like is the most developed/functional for that chip. I'm hoping between the datasheet and the chunks of code that I can find that I can do for it what I did for the w5100. I've read that...

Has anyone on this thread ever fooled around with the ENC28J60 based cards as opposed to the Wiznet w5100 based cards? The price of these things on eBay is rather insane! I just picked up three for $14 shipped off of eBay...

Overkill is my very favorite flavor of kill!

First of all bravo Sir! ANY project which takes 36 temperature sensors must be chocked full of win! Just making sure but you do know that writing STARTCONVO onto the OneWire bus makes all the sensors on the bus take a temperature reading and store the results in their EEPROM (scratchpad)...
