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. Obsolete Product(s) - Obsolete Product(s)

9 Recommendations

  • An integrated antenna is present on the board: – Assembly the board in the application avoiding any shielding of the antenna – Avoid metallic parts close to the antenna – Do not use metallic case
  • Board fixing can be done with 4 screws: – In case of fixing on metallic base insert an insulator foil between the board and the base in order to avoid any potential short circuit Obsolete Product(s) - Obsolete Product(s)
