主要产品
A smart water meter not only measures water flow but uses wireless communication to connect to local or wide area networks, allowing remote location monitoring and infrastructure maintenance through leak detection. Smart water metering systems also enable automatic billing and customer management, including detection and protection against tampering attempts. Smart water meters are battery powered and thus low-power devices play a crucial role in defining system configurations.

我们的产品和解决方案

用于智能水表设计的意法半导体产品 意法半导体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。
