An intelligent multichannel data acquisition (DAQ) system based on the novel integrated circuit of universal sensors and transducers interface (USTI) or USTI-1M-20 with high metrological performances is described in the paper. It can be used with any existing quasi-digital as well as analog sensors and transducers. A parallelism in such systems was realized as time-division channeling and combined channeling, included both: the time- and space- division channeling. The new modified method of the dependent count for frequency (period) measurements lets introduce adaptive features in such DAQ systems. In addition to the self-adaptation capability the sensors in such systems will have self-identification capability due to the TEDS according to the IEEE 1451 standard in the ICs' memory. The described design approach can be used also for creation low cost, high performances multichannel, multifunctional DAQ systems for basic environmental sensing parameters as well as many other custom sensing applications.
