Abstract:
A USN(Ubiquitous Sensor Network) external sensor integration module is provided to enable an interface to generate output signals suitable for input request levels of a USN module according to various types of sensors, thereby integrating independent interface devices necessary for each external sensor into one. A sensor connection port(21) separates various kinds of sensors according to each channel to connect the separated sensors. A converter(2) senses sensing signals of the sensors connected to the sensor connection port, and converts the sensed signals into USN module input signals, then comprises as follows. A front end circuit(22) uniformly converts each sensor signal into voltage signals. An A/D(Analog to Digital) converter(23) converts the sensor signals into digital signals. A controller(24) receives input of the A/D converter to convert into level values suitable for processing conditions of a USN module(3). A D/A(Digital to Analog) converter(25) converts digital output of the controller into analog signals to output the converted signals to the USN module. The USN module receives output of the converter to output the received output as a USN protocol.
