Create a 1-wire device
$250-750 USD
Pagado a la entrega
I want to make a device that will drop into a 1-wire network and provide temp readings just like DS18B20 sensor. But this device would allow you to connect a Thermocouple, Thermistor or RTD.
Device would need to emulate a DS18B20 so that it could be read by the same code we have that reads current DS18B20 sensors.
Device needs to run from 5V.
This job consists of determining the best microcontroller and ADC for the job, would prefer something from the Atmel or Microchip line.
Schematic Layout
PCB Layout
Software to run on the device
PCB Layout needs to be done in Eagle or Altium
PCB will be ordered and the device fully tested before final milestone is released

hi, i am an electrical engineer. i have expertise in embedded system design.i can help you with this project.
Hello, if you don't have space limitations Arduino will best serve the job, i will program the arduino to get the data from k-type thermo couple and will output the data to to a single wire just as DS18B20 or if you d Más

Hi there! I can propose device on Atmel tiny series MCU 8-pin count, 10-bit ADC. I suggest to use thermocouple, with option of software choose type of thermocouple.
Nice project. I have designed a one wire device, but not for temperature. I have over thirty years of experience in mixed signal design and I think this would be a fun challenge! For me it would be either an Atmel, Más
Hello. Does Arduino UNO works fine for you? It does not need PCB layout because its a ready platform. With best regards
I am highly interested in this project and will help you achieve results above and beyond your expectation with a quick turnaround...Hope to achieve next positive feedback from you!!!
