Low-Cost Water Meter Implementation with FRAM Microcontroller Reference Design
This reference design, featuring the MSP430FR4133 FRAM-based MCU, is a fully-functional battery powered magnetic pulse water meter with wired and wireless automatic meter reading (AMR) function. The instantaneous and total flow is displayed on the LCD. This design works in low power mode and reduces CPU engagement, which helps to reduce overall power consumption.
- Magnetic pulse measurement
- 2.9uA standby current
- Non-volatile on-chip FRAM real-time storage
- Support NFC and Sub-1GHz BoosterPack
- Battery voltage monitor
- This end equipment design is tested and includes HW, firmware, GUI, demo and User's Guide
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
