Create a 1-wire device

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

Skills: C Programming, Electrical Engineering, Electronics, Microcontroller, PCB Layout
