DTECH Industrial Grade Wireless Data Transmission 5KM DTU RS232 RS485 Wireless Data Transmit LoRa

1. This product is a LoRa wireless data transceiver using LoRa spread spectrum modulation for high performance, highly reliable,stable,
and low-power wireless data transmission. It provides a high performance, low-cost solution for environments where wiring is not feasible.LoRa is a long-range wireless communication solution, known for its long-distance coverage and low power consumption.It breaks through coverage scenarios that previously required relays. This product defaults to wireless data transmission in the 410.11MHz frequency band,supporting a wireless frequency range of 410MHz-510MHz,with a transmission distance of up to 3 kilometer. Compared to GPRS, 4G solutions, it doesn’t require network access fees (no frequency application required) and offers longer distances than WiFi or Zigbee.Hence, LoRa is increasingly used in industrial serial communications for small data transmission over long distances. LoRa performs excellently in coverage and power consumption, gaining extensive use in IoT applications. This product can achieve one-to-one, one-to-many, or many-to-many data transmission without distinguishing between transmitting and receiving ends.This product provides standard signal interfaces, allowing various application scenarios using LoRa wireless

functionality:

① Wireless meter reading, e.g., smart electric meters, smart water meters, smart gas meters, heat meters, etc.;

② Slowly changing physical quantities (temperature, water pressure, PM2.5, electromagnetic sensors) for

ultra-low-power sensors;

③ Wireless alarms (smoke detectors, infrared thermometers);

④ Remote I/O controllers (lighting control, air conditioning control);

⑤ Industrial applications: industrial CNC machines, industrial automation instruments, long-distance irrigation

equipment, access control, security control systems, highway weighbridge data transmission, commercial

cash registers, and other device connections.

（1）Supports fixed-point transmission, transparent transmission, air wake-up function, and automatic

internal packet transmission.

（2）Communication Distance: The most intuitive perception is that the distance is increased by 3-5 times.

Previously uncovered blind spots for 433MHz wireless products can now be fully covered by LoRa,

offering the ultimate solution for unreliable 433MHz communications.

（3）LoRa demodulation technology can correctly demodulate data even in noisy environments, with a

sensitivity of up to -120dBm.
