WIRELESS MICROSENSOR MOTE
MICA2DOT
MICA2DOT
The MICA2DOT Mote is a third
generation mote module used for
enabling low-power, wireless,
sensor networks. The MICA2DOT
is similar to the MICA2, except
for its quarter-sized (25mm) form
factor and reduced input/output
channels. The following features
make the MICA2DOT better
suited for commercial
deployment;
·868/916MHz or 433MHz 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
·Compatible with MICA2
(MPR400) Mote
·On Board Temperature Sensor,
Battery Monitor, and LED
TinyOS 1.0 is a small, open-
source, energy efficient, software
operating system developed by
UC Berkeley which supports large
scale, self-configuring sensor
networks. The source code and
software development tools are
publicly available at:
http://webs.cs.berkeley.edu/tos
Processor and Radio Platform
(MPR500CA):
The MPR500CA 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 (MPR500CA) can be
configured to run your sensor
application/processing and the
network/radio communications
stack simultaneously. The
MICA2DOT features 18 solderless
expansion pins for connecting 6
Analog Inputs, Digital I/O, and a
serial communication or UART
interface. These interfaces make
it easy to connect to a wide
variety of external peripherals.
Sensor Boards:
Various sensor boards and data
acquisition boards are available
from Crossbow . These boards
connect onto the MICA2DOT
through a ring of 18 solderless
expansion pins. These pins allow
boards to be stacked both above
and below the MICA2DOT
processor radio board. Crossbow
supplies the following expansion
boards:
