Wireless Transmitter 868Mhz Lora Shield for Leonardo, UNO, Mega2560, Duemilanove, Due
The LoRa Shield, designed in the Arduino shield form factor and based on an open-source library, serves as a long-range transceiver with unparalleled capabilities. With this shield, users can transmit data over vast distances at low data rates, making it ideal for applications requiring extensive coverage. It features ultra-long-range spread spectrum communication and exceptional interference immunity while minimizing current consumption.
Utilizing the RFM95W module, the LoRa Shield is tailored for professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, and building automation. By leveraging Hope RF’s patented LoRa™ modulation technique, the shield achieves remarkable sensitivity of over -148dBm using cost-effective components. Its integrated +20 dBm power amplifier ensures an industry-leading link budget, making it optimal for any application requiring range or robustness.
Moreover, LoRa™ modulation provides significant advantages in both blocking and selectivity over conventional techniques, effectively addressing the traditional design compromise between range, interference immunity, and energy consumption. Additionally, the shield supports high-performance (G)FSK modes for systems including WMBus and IEEE802.15.4g, delivering exceptional phase noise, selectivity, receiver linearity, and IIP3. This results in significantly lower current consumption compared to competing devices, enhancing efficiency and extending battery life in various applications.
