Design of a Wireless Sensor Network Node Based on nRF2401

As an important unit composing Wireless Sensor Networks, sensor node normally integrates sensor, data processing unit and communicating module. Power consuming and data transmitting rate are the key factors affecting the quality of it. Regarding the characteristics mentioned, we designed a new wireless sensor network node based on nRF2401. Since the node using low power consumption processor ATmega88 and wireless communication module nRF2401, it guarantees the system operating life and data transmission speed efficiently. Furthermore, the digital thermometer DS18B20 based on 1-wire technology can give the system more concision and more reliability. This node easily applies to Wireless Sensor Networks widely, with its characteristics of low-power, miniaturization and high integration.
