智能燃气表不仅可以测量气体流量，还可以使用无线通信连接到局域网或广域网，以便进行基础设施维护、远程位置监控和自动计费。它们还具有泄漏和冲击检测系统，通过检测紧急情况并在遇到地震活动或气体泄漏的情况下立即远程切断气流，可大大提高安全性。 智能燃气表由电池供电，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，以便克服智能燃气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燃气表所需的电池寿命要求。
