Würth Elektronik has introduced a small, cost-optimized radio module for transmitting meter readings in accordance with the wireless M-Bus standard EN 13757-4. It can be used both as a transmitter for a meter as well as a receiver for a gateway or data collector. Metis-e is based on the SoC CC1310 chipset from Texas Instruments and operates on the 868 MHz frequency band.
The metering radio module from Würth Elektronik has a range up to 1500 meters and, with dimensions of just 12 × 8 × 2 cubic-mm, is more than 50 percent smaller than comparable models on the market. Metis-e is optimized for automatic meter reading and for use in battery-powered devices. The module has two energy-saving modes, requiring 1.6 µA in standby mode and just 200 nA in shutdown mode. The different wM-Bus modes S, T, and C can also be selected to support various applications with different requirements.
This module offers developers great flexibility with its extensive features, which can be accessed via the UART interface. The company also provides a comprehensive user manual and a software development kit for the Metis-e module.
