Features of BLE Bluetooth module:
- Low power consumption;
- Low cost;
- Good compatibility;
- Short-range wireless communication;
Water meter reading method:
- Manual meter reading (pay after using);
- IC card pre-charge (pay before using);
- Use wireless methods (BLE, LoRa, etc., pay before using)
The application of BLE in water meters has realized technological innovation, improved efficiency, and reduced usage costs:
