Arduino LoRa 擴展板 – Dragino LoRa  868M frequency Arduino 專用 Lora  擴展板

Dragino LoRa Shield是Arduino屏蔽外形的远程收发器,基于开源库.LoRa Shield允许用户以低数据率发送数据并达到极长距离。它提供超长距离扩频通信和高抗干扰性,同时最小化电流消耗。

基于RFM95W的LoRa Shield专注于专业无线传感器网络应用,如灌溉系统,智能计量,智能城市,智能手机检测,楼宇自动化等。

使用Hope RF的专利LoRa™调制技术,LoRa Shield可以使用低成本的晶体和材料清单实现超过-148dBm的灵敏度。高灵敏度与集成的+20 dBm功率放大器相结合,可提供业界领先的链路预算,使其成为任何需要范围或稳健性的应用的最佳选择。与传统调制技术相比,LoRa™在阻塞和选择性方面也具有显着优势,解决了传统设计在范围,抗干扰性和能耗之间的折衷。

这些器件还支持包括WMBus,IEEE802.15.4g在内的系统的高性能(G)FSK模式。 LoRa Shield具有出色的相位噪声,选择性,接收器线性度和IIP3,与竞争器件相比,可显着降低电流消耗。

Description

The Dragino LoRa Shield is a long range transceiver on a Arduino shield form factor and based on Open source library.The LoRa Shield allows the user to send data and reach extremely long ranges at low data-rates.It provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

The LoRa Shield based on RFM95W targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on.

Using Hope RF’s patented LoRa™ modulation technique the LoRa Shield can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa™ also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.

These devices also support high performance (G)FSK modes for systems including WMBus, IEEE802.15.4g. The LoRa Shield deliver exceptional phase noise, selectivity, receiver linearity and IIP3 for significantly lower current consumption than competing devices.
