An IEEE 1451 standard transducer interface chip with 12-b ADC, two 12-b DAC's, 10-kB flash EEPROM, and 8-b microcontroller

Plug-and-play mechanism for plain transducers with wired digital interfaces attached to wireless sensor network nodes

“…The comparison of the suggested mechanism with the reported implementations of the IEEE 1451 system (see e.g. Cummins et al (1998) and Stepanenko et al (2006)) shows that the suggested mechanism allows reduction of the required microcontroller code amount by more than 90%, while at the same time allowing exclusion of additional components (such as memory blocks for storing TEDS or additional processing devices for implementing additional smart features). In addition, the evaluation of the suggested P&P mechanism showed that it makes the initial WSN node program independent of the connected sensors -all of the required sensor drivers are retrieved automatically from the WSN by the node after start-up and peripheral identification.…”

IEEE1451.4: A way to standardize gas sensor

“…The family standard IEEE 1451 [5][6][7][8][9][10][11][12][13][14][15][16][17][18], recently approved in some parts, provides the tools for developing plug-and-play transducers and it can be exploited for gas sensors.…”

Highly Adaptive Transducer Interface Circuit for Multiparameter Microsystems

“…Some interfaces are formed monolithically with transducers [12], [15], while others have been developed using field programmable analog arrays [16]. As sensor networks have evolved, many interface circuit with extensive communication capabilities have been introduced [4], [5], [12] including some without sensor readout circuit [17], [18]. System architecture also dictates the signal processing capability required within interface circuits, and some sensor interfaces with full microprocessors have been developed [17], [19].…”

“…As sensor networks have evolved, many interface circuit with extensive communication capabilities have been introduced [4], [5], [12] including some without sensor readout circuit [17], [18]. System architecture also dictates the signal processing capability required within interface circuits, and some sensor interfaces with full microprocessors have been developed [17], [19]. Of this wide range of sensor interface configurations, those with highly specialized capabilities and performance are well suited for large volume products, typically single parameter/ sensor components for industrial and commercial applications.…”
