SDI-12 Interface

This project was a simple RS-232 to SDI-12 interface using a PIC microcontroller. The hardware is just a PIC16F688 with an analog switch and a RS-232 level converter assembled onto some veroboard and mounted inside an old film canister. The interface allows both reading and writing to a wide variety of SDI-12 compatible sensors.
