Paper Thickness Detection


Application Brief:

Previous set of parallel rows of open wheel, each of the above there is a magnet. When there is paper or banknote adopted, the relative position of the magnet and the Hall chip changes, leading to the Hall chip output voltage changes. MCU system by comparing the stored voltage value is compared with the output value, if you find deviations, the alarm.

Application: linear Hall

Recommended type: MT450X series linear Hall
