Wireless Transmitter 433Mhz Lora Shield for Leonardo UNO
The Lora Shield, designed in an Arduino shield form factor and built upon an open-source library, serves as a long-range transceiver offering 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 power consumption.
Utilizing the RFM95W/RFM98W modules, 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 harnessing Hope RF’s patented LoRaTM 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 well-suited for applications prioritizing range and robustness.
Moreover, LoRaTM modulation provides substantial advantages in blocking and selectivity compared to traditional techniques, effectively addressing the trade-offs 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.
