Single-chip smart water meter with dual-band RF and InfraRed port 

Hundreds of millions of mechanical water meters are deployed around the world today. Market pressure pushes water utilities to add intelligence and allow for automated readout and billing on top of water waste control. RF-enabled electronic flow measurement modules provide a cost-effective solution without full meter replacement and are the main building block for fully electronic smart water meters with the impeller principle. This training session will cover four key sub-systems for converting mechanical water and heat meters into a smart meter. The inductive or LC-sensing rotation detection implementation for flow measurement is using our SimpleLink™ CC1350 Wireless MCU and CSD23280F3 FemtoFET™. The Dual-band wireless and InfraRed LED communications, as well as the innovative SW GPIO control of 7-segment LCDs, utilize CC1350 internal hardware resources. All four sub-systems have been optimized for ultra-low power consumption to enable product lifetime longer than 10 years with a single primary battery cell.
