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.
