There has been a proliferation of real-time sensing application due to the recent technological improvements in small, inexpensive, low-power, and distributed “smart” sensor nodes capable of doing a small amount of data processing and storage. Sensor network coordinates a collection of these sensor nodes to enable a high quality detection and measurement network in great details. Sensors come in great variety with different capabilities from different vendors. Besides, there exists a variety of sensors interfaces i.e. analog (capacitive, inductive, and resistive readout), I2C, SPI, UART, for communicating sensor signals. Therefore, it is difficult to provide the required level of integration and functional flexibility which are of great importance in smart-sensor systems. Due to these various interfaces, the design of the versatile sensor interface bus is of great importance. This paper presents a Versatile Sensor Interface Bus (VSIB) architecture which offers network-independent communication interfaces for connecting sensors to microprocessors, instrumentation systems, and control/field networks. It is shown that it is easier to deploy commonly available sensors with various communication interfaces to a multi-sensor module.
