low-frequency half-duplex LoRa

Main Features

Low-frequency half-duplex LoRa technology:

  • USR-LG206-L-P operates in the 398~525MHz frequency band, which is one of the ISM (Industrial, Scientific and Medical) frequency bands commonly used by LoRa technology. Low-frequency band transmission has stronger penetration and longer transmission distance.
  • Half-duplex communication mode means that the device can only send or receive data at the same time, but efficient data exchange can be achieved through reasonable scheduling.

Long-distance data transmission:

  • This product has excellent communication distance performance, up to 3500 meters in open line of sight (some models such as USR-LG206-L-P-H10 can reach 5000 meters), thanks to the long-distance communication capability of LoRa technology.
  • The transmission distance is affected by many factors, including antenna gain, device height, environmental interference, etc.

Low power design:

  • LoRa technology itself is known for its low power consumption. USR-LG206-L-P further reduces power consumption through optimized hardware design and software algorithms, which is suitable for IoT devices that need to run for a long time.

Multiple communication protocol support:

  • Supports point-to-point communication protocol, and also supports concentrator communication protocol (must change firmware), which is convenient for building complex IoT networks.
  • Supports AT command configuration, which is convenient for users to set up and debug devices through serial ports.

Rich interfaces and expandability:

  • Provides RS232/485 interface for easy connection with various sensors, controllers and other devices.
  • Optional expansion modules such as GPS module, SD card module, etc. to meet the needs of different application scenarios.

High reliability and protection level:

  • Uses hardware watchdog technology to ensure that the device can automatically restart in abnormal situations to avoid crashes.
  • Supports advanced protection functions such as 4-level anti-static, 3-level power surge protection and hardware watchdog to improve the reliability and stability of the device.

Technical parameters

  • Working frequency band: 398~525MHz
  • Communication distance: up to 3500 meters (some models can reach 5000 meters)
  • Interface type: RS232/485
  • Power supply: 5~36V DC
  • Receive sensitivity: -138.5dBm (typical value)
  • Protection level: support 4-level anti-static, 3-level power surge protection, hardware watchdog, etc.

Application scenarios

USR-LG206-L-P has a wide range of applications in many fields due to its long-distance, low power consumption and high reliability:

Smart city:

  • Used for data collection and transmission in scenarios such as smart parking, smart lighting, and environmental monitoring.

Agricultural monitoring:

  • Monitor environmental parameters such as soil moisture and temperature to help farmers achieve precise irrigation and scientific management.

Environmental monitoring:

  • Used for data collection and remote transmission in environmental protection fields such as air quality monitoring and water quality monitoring.

Industrial Internet of Things:

  • Connect various sensors and equipment in the factory to achieve real-time monitoring and analysis of production data.

Smart home:

  • Although it is not its main application scenario, it can also be used in some smart home devices that require long-distance communication.
