LoRa data transmission terminal

Introduction:

Shenzhen Yima Xinnuo has developed a LoRa data transmission terminal, a universal communication interactive device designed and manufactured based on LoRa RF chips. The product integrates two industrial standard RS485 channels, which transmit the data that wired devices need to transmit to the device through RS485 communication lines, and then transmit the data wirelessly. It supports multiple protocols and achieves data transmission between wired and wireless devices.

Characteristics of LoRa data transmission terminal:

(1) LoRa wireless communication technology reduces user wiring costs;

(2) Wireless spread spectrum communication technology with strong anti-interference ability;

(3) Ultra long distance high transmission, visual communication distance of 10Km, urban environment of 3-5km;

(4) A graphical configuration interface for remote management of user terminals and gateways;

(5) Support access to thousands of user terminals;

(6) Supports Ethernet/4G uplink connection;

(7) Support external serial port modules to connect users to other mature terminals;

(8) Support providing data push services and message subscription publishing services to third-party application platforms;

(9) Support remote parameter configuration.

LoRa data transmission terminals are widely used in areas such as the Internet of Things, centralized meter reading, and industrial control. Currently, the main focus is on measuring water, electricity, gas, heat, and other related items. Because the cost of meter reading is low and easy to implement through LoRa wireless transmission. Not only can it receive accurate data, but it also maintains low power consumption under the premise of bidirectional interaction, achieving long-term battery standby.
