A simple multi parameter measurement system using multi transducer

The present article portrays a design and implementation of microcontroller based system for different physical parameter measurement using multi transducer with very high accuracy. For maintaining accuracy of the system a novel method is used which is multi channel direct sequence spread spectrum technique and it is also used as a filter for eliminating low frequency noise to maintain accuracy. It also meets the demand of development of a microcontroller based embedded system for physical parameter measurement. The system should monitor and provides data for examining with high accuracy. The system is initially tested with two transducers but there is a provision to incorporate eight number of transducer with same accuracy.
