30 30  SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous [[serial communications>>url:https://en.wikipedia.org/wiki/Serial_communication]] protocol for intelligent sensors that monitor environment data. SDI-12 protocol is widely used in Agriculture sensor and Weather Station sensors.
