Minimum gas flow rate: 0.000 m3/hr
No. of tampers supported: 4
Maximum tariff scheduling supported: 4
(with minimum time difference between
every tariff is 1 Hr in ascending order)
WMBUS stack running on STM32L
microcontroller available on board
Supports Sub GHz SRD bands: 169 MHz (N
mode), 868 MHz (S mode)
December 2013
A very low-power and high performance RF
transceiver "SPIRIT1" used for wireless
communication
Windows application available to configure
WMBUS parameters at concentrator side
and reading various metering data received
from the gas meter
Android application available for accessing
various parameters of meter from dual
interface EEPROM using smartphone
through NFC
RoHS compliant
The STEVAL-IPG001V1 demonstration 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, tariffwise 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.
