Experimental and theoretical studies on a resolution enhanced sensing system based on multisensor successive approximation

A new system for highly-accurate sensing is described that uses a multiple of inaccurate sensors. The system is based on principles of successive approximation and statistical estimation. The concept has been implemented in a microcontroller based real-time system. Experimental results for temperature measurement have demonstrated significantly improved accuracy over a conventional single-sensor system. Theoretical analysis supports experimental results. The concept is general and extends to other measurands.
