Introduction

The 433M wireless module is a long-distance LoRa wireless gateway. As a wireless technology, LoRa is based on the Sub-GHz frequency band to make it easier to communicate with lower power consumption over a long distance. It can be powered by batteries or other energy harvesting methods. Lower data rates also extend battery life and increase network capacity. The penetration of LoRa signals into buildings is also very strong. These technical characteristics of LoRa are more suitable for low-cost large-scale IoT deployments.



Features and technical specifications

1. 20dB gain;

2. Up to 15km (line of sight);

3. Use star connection;

4. Support link data encryption;

5. The maximum capacity is more than 200 sets;

6. Support load balancing between channels;

7. Air interface physical layer: TDD+FDD;

8. Communication protocol: private protocol;

9. The working frequency band is 470~510MHz, which is divided into 2 groups of sub-bands, which can be selected by the gateway;

10. Support two working modes: real-time communication mode and energy-saving mode;

11. When 200 terminals are connected at the same time, poll all modules within 60 seconds at most;

Without affecting the gateway polling, the burst random two-way communication initiated by the gateway or module can be carried out correctly at an average of 20 times per minute, and it can automatically delay and resend when encounters conflicts. The total delay of random burst communication is less than 1s;

12. Support real-time configuration parameters to the terminal, and support terminal alarm information to be uploaded to the gateway in real time;

13. Power supply: DC +5v;

14. When the external power supply is interrupted, the internal power supply lasts for 20 minutes;

15. With web function, you can configure parameters and query status via web;

16. Working environment:

Working conditions: temperature -40℃~85℃; humidity 0~95﹪RH, non-condensing;

Storage conditions: temperature -55℃~90℃; humidity 0~99﹪RH, non-condensing;
