SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. These instruments are typically low-power (12 volts), are used at remote locations, and usually communicate with a data logger or other data acquisition device.

SDI-12 is a standard for interfacing data recorders with microprocessor-based sensors. SDI-12 stands for serial/digital interface at 1200 baud. This document describes the electrical interface, the communications protocol, and the timing requirements for SDI-12 …

This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the SDI-12 communication protocol between an Arduino-based …

SDI-12 was created in 1988 by a group of private firms and the U.S. Geological Survey's Hydrologic Instrumentation Facility (USGS/HIF). The key requirement was a low power standard interface between the data recorder and intelligent, micro-processor based sensors at …

2014年9月8日 · An SDI-12 intelligent (‘smart’) sensor is microprocessor-based, enabling it to take a recording (data sample), apply computations to that reading, and then use the SDI-12 standard to return the data scaled to engineering units. Some smart sensors can …

2024年7月19日 · SDI-12 sensors are crucial for providing timely and accurate environmental data, essential for informed decision-making in fields like agriculture, water resource management, and climate monitoring. Their low power requirements and efficient data transmission over a simple setup make them ideal for deploying in extensive and remote sensor networks.

The serial communication protocol SDI-12 is a standard in meteorology and hydrology that enables the connection of energy-efficient sensors to various data loggers. Due to its low power consumption, SDI-12 is ideal for solar-powered weather stations, as it allows for precise measurements such as temperature, humidity, and precipitation without ...

What is SDI-12? SDI-12 is a standardised interface for connecting digital sensors to a master device – typically an SDI-12 compatible data logger, wireless node or computer. SDI-12 defines both the digital communications and sensor power standards.

SDI-12 is a 1200 baud communications protocol that supports many smart sensors, probes, and devices. The data logger supports SDI-12 communications through two modes: transparent mode and programmed mode. In transparent mode, users can easily set up and troubleshoot sensors by manually issuing commands and viewing the full sensor response.

SDI-12 is a standard for interfacing data recorders with microprocessor-based sensors. SDI-12 stands for serial/digital interface at 1200 baud. This document describes the electrical interface, the communications protocol, and the timing requirements for SDI-12 …
