智能水表不仅可以测量水流量，还可以使用无线通信连接到局域网或广域网，从而实现远程位置监控和基础设施维护（通过泄漏检测）以及自动计费和客户管理，包括检测和应对篡改企图。智能仪表由电池供电，因此低功耗设备在定义系统配置方面起着至关重要的作用。

ST通过独特的系统级应用技术和引人注目的半导体产品、评估板和软件开发套件组合为设计师提供支持，以便克服智能水表应用所带来的设计挑战。

我们的超低功耗sub-GHz RF通信解决方案支持所有主要协议：长距离协议，其中包括WM-BUS和专用的LPWAN协议，如LoRa和Sigfox，以及短距离协议，如双接口NFC/RFID标签与超低功耗蓝牙（BLE）和802.15.4片上系统。连同超低功耗STM8L或STM32L微控制器，我们的解决方案可帮助应用满足智能水表所需的电池寿命要求。
