LoRaWAN Smart Water Meter

Introduction:

Yima Xinnuo has recently applied LoRa communication technology and LoRaWAN standards to smart water meter solutions, enabling remote, efficient, and intelligent management of water metering equipment for public utilities. Real time monitoring of water meter traffic through LoRaWAN networking. Form a secure sensor network with Sensing Edge gateway for flexible deployment.

The choice of LoRa technology is due to its openness, ease of deployment, and flexibility. LoRaWAN adopts the LoRa Alliance standardized protocol, which can truly achieve interconnectivity. Water meter end customers can use LoRaWAN protocol to compensate for the application limitations brought by NB IoT technology, while helping customers save costs, improve meter reading management efficiency, and save water resources.

Technical parameters:

1. Base material: copper shell dry type;

2. Operating frequency: 470MHz;

3. Range ratio Q3/Q1: R80;

4. Transmission distance: open visual distance of 500-2000 meters, with a building of 30 floors that can be copied;

5. Battery voltage: 3.6V;

6. Modulation method: LoRa modulation;

7. Protection level: IPX6/8.

Functional advantages:

1. Ultra long distance communication. Test coverage range>11.5 KM;

2. Ultra low power consumption. Sleep current<1.8uA;

3. Ultra high receiving sensitivity, reaching -140dBm;

4. Large network capacity, network flexibility, and low cost.

LoRaWAN smart water meters have successfully helped customers reduce costs and achieve smart public utility management through the use of low-power, wide coverage, and high meter reading success rate technology solutions.
