Capacitance sensor tag quantitative displacement (weight) detection system
Insert an elastic body between the upper and lower electrodes, and measure while fixing the area and dielectric constant of the electrodes!
The system detects objects placed on a tag by their weight, functioning as a quantitative displacement (weight) detection system. When an object is placed on the electrode, the elastic body between the electrodes compresses, reducing the distance between the two electrodes. As the distance between the electrodes decreases, the capacitance value increases. This allows for the detection of whether an object is present. Additionally, if the object has a constant weight, it is possible to detect quantity by pre-establishing the capacitance value. 【Features】 ■ Battery-less sensing ■ Ability to manage various weights from a distance ■ Inventory management based on the weight on the tag ■ Alerts when the weight falls below the reorder point *For more details, please refer to the PDF document or feel free to contact us.
