STMicroelectronics Introduces MotionBee Platform for Remote Motion Control

a leader in MEMS and wireless technologies, has introduced
MotionBee, a complete, ready-for-use platform that combines
state-of-the-art motion sensing with ZigBee wireless technology in a
single ultra-compact module. Boasting low power consumption and high
level of integration, ST’s MotionBee enables system developers to
quickly and cost-effectively build wireless sensor networks for remote
motion recognition and tracking in many different application areas,
including healthcare, security, industrial control and environmental

first-generation MotionBee module integrates ST’s market-proven 3-axis
digital-output MEMS accelerometer with a ZigBee platform from Ember
Corporation that includes the EM250 System-on-Chip, a 2.4GHz, IEEE
802.15.4-compliant radio transceiver and processor, together with the
EmberZNet PRO(TM) ZigBee networking software. The module detects
accelerations in the selectable range of +/- 2g and +/- 6g and
transmits the information to a central connection point (star topology)
or every other node (mesh topology) in a ZigBee wireless network. The
module is fully programmable and its small size (49 x 27 x 5 mm) makes
the deployment easier, such as in wearable medical or sports equipment.

specifically the requirements of remote sensing and control systems,
ZigBee technology enables the implementation of broad-based wireless
mesh networks that are able to run for months on inexpensive primary
batteries, representing a viable alternative to costly hard-wired
systems. The first-generation MotionBee modules are optimized for
designs that require long battery life, a low external component count,
and a reliable, proven, industry-standard networking solution.

complete and cost-effective remote motion control platform enables
wireless sensor networks in a variety of existing and emerging
applications, such as vibration monitoring and detection in different
indoor and outdoor environments, automated navigation systems, or
bio-sensor networks in remote-healthcare scenarios.

first MotionBee device, the SPMB250-A1, is available now, with samples
priced at $60. An evaluation kit is also available, with two
pre-programmed modules and a ZigBee dongle for integration with a PC.
