Water resources on a global scale are limited and the consumption of fresh water needs to be monitored and charged on an individual basis in state-of-the-art homes and residential buildings. In this home-based water meter design, the flow sensor ensures accurate measurements while the MCU provides a user interface with an LCD control to allow customers to view consumption data.

System Benefits:

  • Includes LCD control and touch interface
  • Ease of use – the MCU integrates several features such as RTC and USB for maintenance
  • MEMS solid-state flow sensor provides accurate measurements




  • Water meter
