TelosB

Crossbow’s TelosB mote (TPR2400) is an open source platform designed to enable cutting-edge experimentation for the research community. The TPR2400 bundles all the essentials for lab studies into a single platform including: USB programming capability, an IEEE 802.15.4 radio with integrated antenna, a low-power MCU with extended memory and an optional sensor suite (TPR2420). TPR2400 offers many features, including:
• IEEE 802.15.4/ZigBee compliant RF transceiver
• 2.4 to 2.4835 GHz, a globally compatible ISM band
• 250 kbps data rate
• Integrated onboard antenna
• 8 MHz TI MSP430 microcontroller with 10kB RAM
• Low current consumption
• 1MB external flash for data logging
• Programming and data collection via USB
• Optional sensor suite including integrated light, temperature and humidity sensor (TPR2420)
• Runs TinyOS 1.1.10 or higher

The TelosB platform was developed and published to the research community by UC Berkeley. This platform delivers low power consumption allowing for long battery life as well as fast wakeup from sleep state.
Though the TPR2400 is an uncertified radio platform, it is fully compatible with the open-source TinyOS distribution.

TPR2400 is powered by two AA batteries. If the TPR2400 is plugged into the USB port for programming or communication, power is provided
from the host computer. If the TPR2400 is always attached to the USB port no battery pack is needed.

TPR2400 provides users with the capability to interface with additional devices. The two expansion connectors and onboard jumpers may be configured to control analog sensors, digital peripherals and LCD displays.

TinyOS is a small, open-source, energy-efficient software operating system developed by UC Berkeley which supports large scale, selfconfiguring sensor networks. The source code software development tools are publicly available at: http://www.tinyos.net
