Description
Technical Field
The invention belongs to the field of garbage classification, and relates to an Internet of things scale and a method for eliminating key interference.
Background
In the existing integrated internet of things scale (the operation buttons and the weighing platform are in the same plane), in the weighing process, clicking the button on the operation interface can cause the pressure sensed by a pressure sensor of the scale to change, so that the weighing result changes due to key operation. For example, when garbage with the weight of 1.50kg is weighed on the integrated internet of things scale, the weight is displayed to be 1.50kg, but when the garbage is pressed, the weight when the garbage is pressed is displayed on the display screen due to the influence of the pressure of the pressed button, and the displayed weight is the sum of the weight and the pressure of the weighed garbage.
When the button is clicked, the pressure sensor senses the pressure of the button, so that the weight data displayed on the display screen is not the accurate weight of the weighing object (including the finger pressure), and the weight data displayed on the display screen is rapidly changed due to the change of the finger pressure in the pressing process. Therefore, the current technical method has obvious defects in terms of display accuracy and reading stability.
