IRIS 2.4 GHz

The IRIS is a 2.4 GHz Mote module used for enabling low-power, wireless sensor networks. The IRIS Mote
features several new capabilities that enhance the overall functionality of Crossbow’s wireless sensor networking
products.
Product features include:
• Up to three times improved radio range and twice the program memory over previous MICA Motes
• Outdoor line-of-sight tests have yeilded ranges as far as 500 meters between nodes without
amplification
• IEEE 802.15.4 compliant RF transceiver
• 2.4 to 2.48 GHz, a globally compatible ISM band
• Direct sequence spread spectrum radio which is resistant to RF interference and provides inherent data security
• 250 kbps data rate
• Supported by MoteWorks™ wireless sensor network platform for reliable,
ad-hoc mesh networking
• Plug and play with Crossbow’s sensor boards, data acquisition
boards, gateways, and software

MoteWorks™ enables the development of custom sensor applications and is specifically optimized for low-power, battery-operated networks. MoteWorks is based on the open-source TinyOS operating system and provides reliable, ad-hoc mesh networking, over-theair- programming capabilities, cross development tools, server middleware for enterprise network integration and client user interface for analysis and configuration.

Processor & Radio Platform
The XM2110CA is based on the Atmel ATmega1281. The ATmega1281 is a low-power microcontroller which runs MoteWorks from its internal flash memory. A single processor board (XM2110) can be configured to run your sensor application/processing and the network/radio communications stack simultaneously. The IRIS 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
Crossbow offers a variety of sensor and data acquisition boards for the IRIS Mote. All of these boards connect to the IRIS via the standard 51-pin expansion connector. Custom sensor and data acquisition boards are also available. Please contact Crossbow for additional information.
