Why is the LoRa module chosen for the application of industrial AMR(Automatic Meter Reading) wireless modules?

Industrial wireless Automatic Meter Reading (AMR) eliminates the need for wiring compared to traditional wired meter reading methods. Wireless modules can be easily installed on equipment that needs to be monitored, providing a more convenient way of meter reading, thereby reducing the cost and workload of maintenance and installation. In addition, wireless modules can achieve remote meter reading and automatic integration, without distance restrictions, making monitoring more convenient without the need for manual meter reading. This approach enables automatic meter reading and data collection, enhancing the flexibility and operability of the system.

The advantages of choosing the LoRa module for industrial AMR include:

1. Long-distance communication needs: In industrial environments, meter reading points are often located far away, and traditional wireless communication technologies often cannot cover these points. The LoRa module has a far transmission distance, capable of covering several kilometers or even tens of kilometers, solving the long-distance communication needs that traditional communication technologies cannot meet.

2. Stable communication in complex environments: There are a large number of electromagnetic interference sources in industrial environments. Traditional wireless communication technologies may be interfered with, leading to unstable communication. The LoRa module uses low-power modulation technology and has strong anti-interference ability. It can maintain a stable communication connection in complex environments, solving the communication problems in industrial environments.

3. Low power design: Industrial AMR often needs to operate for a long time, and there are many devices, so power consumption is an important consideration. The LoRa module uses low-power communication technology, which can extend the battery life of the device, reduce the frequency of battery replacement, and solve the problem of power management.

4. Large-scale deployment and high scalability: Industrial AMR often needs to connect large-scale devices and may need to be expanded further in the future. The LoRa network has high scalability and can support the connection of large-scale devices. At the same time, the LoRa module has a larger data transmission capacity, which can meet the large amount of data transmission needs in industrial environments, solving the problems of large-scale deployment and high scalability.

5. High cost-effectiveness: For industrial AMR applications, the overall cost is an important consideration. The LoRa module has a lower cost, which can reduce the investment in equipment and communication infrastructure. At the same time, the low-power design can also reduce energy consumption costs, solving the problem of cost-effectiveness.

The LoRaCC68 LoRa wireless module produced by NiceRF, is designed with the LLCC68 chip from Semtech. It has a built-in 64KHz crystal oscillator, receiving current (less than 5mA), and a sleep current (1.9uA). In a low power situation, it can wake up the microcontroller regularly. Its small size is equipped with an output power of 22dBm (160mW), and the transmission distance can reach 4-6 kilometers. With the integrated relay function, it can cover 10-20 kilometers, fully meeting the wireless transmission application requirements of industrial AMR.
