AVR Firmware Development

I need something similar to the attached document to get ohm readings from a water probe. However I don't need datalogging or temperature readings. I just need the device to behave like an I2C slave and reply to requests with the calculated ohm readings. As in the schematic in the document there will be two probes. Attiny441 /841 or Attiny24 would be preferred but other avr devices could be used if needed.

Please contact me with any questions.
