Do you understand the technical implications of the LoRa module?

With the development of the Internet of Things technology, many Internet of Things technologies have emerged. Among them, the more widely used technology is the lora technology. The application of the lora module in various industries has made the lora technology popular among many users. Richerlink will come with you to understand the lora module.

The Lora module is a universal communication interaction device designed and manufactured based on LoRa RF chip. It integrates two industrial standard RS485, transmits the data that the wired device needs to transmit to the device through the RS485 communication line, and then transmits the data wirelessly. Multiple protocols for data transfer between wired and wireless devices. Currently, LoRa operates primarily in free global bands, including 433, 868, and 915 MHz.

Long-distance, low-power consumption is the biggest advantage of the lora module. The high sensitivity of the receiving data of the lora module solves the contradiction of the transmission distance due to low power consumption. The sensitivity of the receiver of the LoRa module is due to the direct sequence spread spectrum technique. LoRa uses a high spreading factor to achieve higher signal gain. Generally, the signal-to-noise ratio of FSK needs 8dB, while LoRa only needs -20dB.

The Lora module IOT-L2S-B has a wide range of applications, such as wireless meter reading, electrical safety, energy efficiency management, etc. It is completely feasible for some companies to use LoRa modules to build small private networks to achieve some applications. of.
