Rotary smart water meter with wM-Bus and LoRaWAN reference design
TIDA-011019
概覽
This reference design, featuring the CC1312R7 and MSPM0L2117 MCUs, is a fully functional battery powered rotary smart water meter. The instantaneous and total flow is updated on the always on LCD display and sent out in a C-mode telegram over OMSv4.2.x wM-Bus protocol; while the rotary sensing and magnetic tampering detection are also implemented and optimized for minimal power consumption.
特點
- Always-on LCD display with up to 4×26 or 8×22 segments
- 3.9µA standby current: 42 active LCD segments + 0.03µA for power switch stand-by + 0.9µA CC1312R7 with pulsed output (rotation sensing not included)
- Inductive, and optical sensing support in a fourlayer, 50mm diameter circular FR4 PCB
- IrDA comms port and magnetic tamper detection
- OMS wM-Bus v4.2.x or later support with optional LoRaWAN radio (time-multiplexed)
- Population options for load switch powering an external LoRaWAN radio and a SPI flash device
