SPIDER Automation 915MHz LoRa Shield | RFM95W/RFM98W Long-Range Transceiver | For Arduino Microcontrollers
Description
The SPIDER Automation 915MHz LoRa Shield is a professional-grade wireless transceiver designed in a stackable Arduino shield form factor. Powered by open-source libraries and built around the high-reliability RFM95W/RFM98W module, this shield allows developers to transmit data across extreme distances at low data rates while minimizing power consumption and maximizing noise immunity.
Engineered for professional wireless sensor networks—such as automated irrigation systems, smart metering, and building automation—the shield combines a high receiver sensitivity of over -148dBm with an integrated +20 dBm power amplifier. By leveraging Hope RF’s patented LoRa spread spectrum technology alongside high-performance (G)FSK modes, it successfully resolves traditional design trade-offs between communication range, interference resistance, and energy efficiency.
Key Features
- RFM95W/RFM98W Transceiver Core: Delivers ultra-long-range spread spectrum communication with superior blocking immunity and selectivity.
- 915MHz Operating Frequency: Factory pre-configured to operate reliably on the 915MHz frequency band for regional network requirements.
- High-Sensitivity RF Front End: Achieves receiver sensitivity down to -148dBm, yielding an exceptional link budget for challenging environments.
- Advanced Packet Engine: Supports packet payloads up to 256 bytes complete with built-in cyclical redundancy check (CRC) validation.
- Automated Channel Sensing: Features automated RF sensing, channel activity detection (CAD), and ultra-fast automatic frequency control (AFC).
- Onboard Diagnostic Sensors: Includes a built-in temperature sensor and low battery indicator for remote node health monitoring.
Benefits
- Extends Transmission Range: Reaches vast distances that conventional RF communication shields cannot achieve under similar power limits.
- Resists Environmental Interference: Advanced modulation techniques prevent data packet loss in electromagnetically congested areas.
- Optimizes Battery Longevity: Low current consumption profiles preserve power in remote, unmonitored sensor node installations.
-
Simplifies Hardware Integration: Direct stackable form factor mates cleanly onto Arduino Uno, Mega2560, Leonardo, and Due development boards.
Applications
-
- Smart Agricultural Irrigation: Deploying wireless soil moisture and weather monitoring nodes across expansive farming fields.
