27 27  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.

29 29  SDI-12-LB has SDI-12 interface and support 12v output to power external SDI-12 sensor. It can get the environment data from SDI-12 sensor and sends out the data via LoRaWAN wireless protocol.
