AERINOS ADS-270

Overview

Introduction

ADS-270 is an ultra low power, battery powered end node for the LoRa network. The unit is available for the 433MHz, 868MHz and 915MHz bands. It incorporates two inputs, one digital with pulse counter capability and one analog, as well as multiple excitation options for powering transducers. A D-size Lithium Thionyl battery provides autonomous operation for over 10 years.

SDI-12 Serial Bus

SDI-12 is an asynchronous, ASCII, serial communications protocol that was developed for intelligent sensor instruments that typically monitor environmental, structural engineering and precision agriculture data. The communication is achieved by digital communications. The addressing system allows data recorder to communicate with several microprocessor-based sensors over a single line. ADS-270 is compliant to the SDI-12 Standard Version 1.2 and supports extended commands for sensor configuration, in terminal mode. ADS-270 can collect data from several SDI-12 sensors for a total amount of 8 measurement channels.

RS-485, MODBUS

ADS-270 supports acquisition from sensors with RS-485 interface, using the popular MODBUS protocol (RTU & ASCII). Up to 8 measurement channels from several sensors are supported.

Transducer excitation

The unit provides multiple excitation options for measuring transducers.
