Abstract
The researches about the hardware and the software implementing ubiquitous sensor network have great rush in recent years. This paper deals the development of a sensor node with the dual interface which also has an RF wireless interface while has an Bluetooth interface used widely in present. This sensor node includes a Atmeg32 microcontroller, a Bluetooth module, a RF module. a temperature-humidity sensor. and I also develop the F/Ws controlling each modules with C language using GCC compiler. The sensor node developed can reaches 15m with Bluetooth interface and 60m with RF interface. It works stably with the voltage above 5V and it consumes currents 21mA average in idle mode, 63mA average in active mode.
