Four-channel temperature controller

[Catcatcat]

I bring to your attention a project to study the work with temperature sensors DS18b20 and how the finished design.

Four independent channels of temperature control, can simultaneously connect 16 temperature sensors DS18B20 with the removal of up to three hundred meters. You can choose to adjust the sensor is connected to the device. Each channel can operate in either heating or cooling mode. The range of temperature control up to 125.0 -55.0 Celsius. The controller for temperature measurement uses a library ds18b20.h. Library performs all functions related to servicing network of 16 sensors, as well as the ability to add and replace if necessary damaged. To display the library indic_4led.h. The minimum number of parts used.

Implementation project in MPLAB IDE v8.90, MPLAB XC8 C Compiler V1.12.
The project is in the attachment. If you have any questions do not hesitate to ask. Additional description can be read on my website

excellent, a very nice project.

thanks for sharing it

[solutions]

Write it up for Nuts and Volts - they'll pay you for it

[puta]

Awesome..!

Good work Mate  !!!

[metal]

Do you have PCBs to sell?

[Catcatcat]

There is an option PCB format PCAD-2006 and Gerber, which option would suit?

[Old_but_Alive]

i would also be interested in a couple of bare pcb,s

[metal]

I did not mean I wanted to make those PCBs.
I want ready PCBs.

If we can setup a group buy for PCBs and components, we can get them for cheap.

[Catcatcat]

Purchased from the Ukraine, several printed circuit boards, I think it is useless. I ordered their production in China, there are easier and cheaper to manufacture. If necessary I can help make order, and you will pay and receive. In an attachment, Gerber files from writing to order production. Just a word of caution, it is a universal circuit board is designed for multiple devices.

It is a complete circuit diagram of the PCB

[metal]

Ok, how much does it cost for each PCB.

[Catcatcat]

Printed circuit board itself is inexpensive, the cost of expensive pre-production and transportation costs. The more order, the cheaper the cost per unit. I can link you to the manufacturer, and they will be given to you an invoice.

On the number of 200 units, the cost turned in $ 0.7

compiler error,

anyone have proteus simulation?

Thanks

thanks
i have to study mplabx, i am new about it.

project can easily be transferred to MPLABX

  now i am going to new world with mplabx.

i was trying to simulate with proteus, compile file included.
