製品概要
概要
The STEVAL-IPG001V1 evaluation board is a fully functional gas meter demonstration board. It is interfaced with OMRON gas sensor and able to read/write and display various parameters on LCD e.g. configuration parameters, maintenance parameters, total consumption parameters, tariff-wise consumptions, 4 types of tampers etc.
The STEVAL-IPG001V1 also manages maximum demand (MD) calculation and communication with dual interface EEPROM (RF and I2C interface). SPIRIT-RF Sub GHz module is also supported by the board and WMBUS protocol stack is running on STM32L Microcontroller available on board.
The STEVAL-IPG001V1 also has provision of controlling gas valve by driving a motor. Connectors for external seismic detector, IrDA, STRNFC module are available for future use. Similarly footprints for external RTC, temperature sensor, USB connector are also available on the board.
