Executive Summary

Wireless Sensor Networks (WSN) has become increasingly important in recent times. Sensor nodes are the building blocks for a typical WSN. Due to their limited computational, communication and energy abilities, the sensor nodes serve as the deciding factor for a given network design. As the fabrication technology improves, highly powerful, yet energy efficient, components are available to realize a WSN while keeping the cost at an affordable level. This paper introduces a novel wireless sensor node based on the powerful 8-bit Atmel ATMega128L Micro-Controller Unit (MCU) equipped with the CC2420 transceiver having complete compatibility with the IEEE802.15.4.
