For every sensor , there are a signal amplifier , filter circuit and date processing microprocessor to constitute a sensor - based system . each sensor - based system are controlled and coordinated by a master single chip microprocessor system by means of interior communicating 針對每種參數(shù)的檢測傳感器,分別配用了相應(yīng)的信號放大電路、濾波電路和檢測數(shù)據(jù)處理的專用單片機(jī)系統(tǒng),使各個參數(shù)的檢測自成系統(tǒng)。
