MICA2
The MICA2 Mote is a third
generation mote module used for
enabling low-power, wireless,
sensor networks. The MICA2
Mote features several new
improvements over the original
MICA Mote. The following
features make the MICA2 better
suited to commercial deployment:
· 868/916MHz, 433 or 315MHz
multi-channel transceiver with
extended range · TinyOS (TOS) Distributed
Software Operating System v1.0
with improved networking stack
and improved debugging
features · Support for wireless remote
reprogramming · Wide range of sensor boards
and data acquisition add-on
boards ·Compatible with MICA2DOT
(MPR500) quarter-sized Mote
Processor and Radio Platform
(MPR400CB):
The MPR400CB is based on the
Atmel ATmega 128L. The
ATmega 128L is a low-power
microcontroller which runs TOS
from its internal flash memory.
Using TOS, a single processor
board (MPR400CB) can be
configured to run your sensor
application/processing and the
network/radio communications
stack simultaneously. The
MICA2 51-pin expansion
connector supports Analog Inputs,
Digital I/O, I2C, SPI, and UART
interfaces. These interfaces
make it easy to connect to a wide
variety of external peripherals.
Sensor Boards:
Various sensor and data
acquisition boards are available
from Crossbow . These boards
connect to the MICA2 through
a surface mount 51-pin connector.
Crossbow supplies the following
sensor boards:
· MTS101CA Photocell/
Thermistor/Proto and
Experiment Board · MTS300CA/MTS310CA Photocell,
Thermistor, Microphone,
Sounder, Magnetic (310 only),
Acceleration (310 only) · Contact Crossbow for
information on other boards
Base Stations:
A base station allows the aggregation of
sensor network data onto a PC or other
computer platform. Any MICA2 node
(MPR400CB) can function as a base
station by plugging the MPR400CB
processor/radio board into a standard
PC interface board, known as the Mote
Interface Board (MIB510CA). The
MIB510CA provides a serial interface for
RS-232 as well as a parallel port
programming interface for the Motes.
Crossbow also offers a stand-alone
gateway solution, the MICA-WEB for
both TCP/IP-based Ethernet networks
and serial networks.
