I have been using the DS18b20 in a 3-wire configuration, but moving forward it would be easier to have a sensor on the I2C bus so as to simplify the wiring, programming, and communication. Anyone know of sources or manufacturers of I2C bus waterproof temperature probes?

Doesn't that mean going from 3 wires to 4? GND, SDA, SCL, & Vcc
It may reduce pin count and indeed programmatic complexity.

Actually going from VCC, GND, SDA, SCL, and One-Wire to just VCC, GND, SDA, and SCL. Not only eliminating the one-wire connection from the cable, but also from the entire project and the pull-up resistor.
But the question is not how to design my project, but where to get the parts...providing they even exist.
