Aiming at demand of measuring weak voltage signal acquisition and analysis for a new type of bromide ion concentration measuring apparatus in drinking water

design a collection system

including signal acquisition and upper PC display section. Weak signal of sensor output is amplified and filtered and then collected by C8051F310 MCU comes with A / D converter collects and send to Lab VIEW compiled upper PC through serial port

upper computer receives data

analyze and display bromate concentration values. Experiments show that this type of acquisition system is stable and reliable

it can be used as data acquisition system for bromide ion concentration measuring device in drinking water.
