Description
SPMB250-A1 board is a ready-to-use wireless
acceleration sensor based on an IEEE 802.15.4
compliant radio. It is designed to enable
development of applications for remote motion
monitoring in wireless sensor networks systems.
The board is based on the ZigBee® module
SPZB250 which performs both the RF radio and
controlling functions and the three axis linear
accelerometer sensor LIS3LV02DL.
The ZigBee® module contains the SN250 SoC
integrating a fully compliant 802.15.4 radio
together with a microcontroller that can be used to
elaborate sensor data and networking
functionalities. SN250 can be programmed to run
the EMZNET ZigBee® protocol stack from Ember
Corporation. The module is programmable thanks
to the SIF connector available on the SPZB250
module.
The LIS3LV02DL three axis accelerometer is a
low power low voltage linear accelerometer with
digital output that can operate in the user
selectable range +/-2 g or +/-6 g and with
programmable data rate.
The controller inside SPZB250 module handles
all the networking functions and it can be used to
implement custom procedures to elaborate and
send data collected by the acceleration sensor.
The board is ready-to-use, requiring only an
external power supplier to connect to the
integrated standard two pole connector. A switch
is present in series to the supply connection to
power on / off the board.
