About this product
An educational digital scale built around a 10 kg load cell and an HX711 amplifier module, with a number display and a tare button. The load cell bends slightly under weight and the HX711 measures that small change precisely. After calibration with a known weight, the display shows the weight in grams. This is a learning project, not a certified weighing instrument. An Arduino Uno is required and is not included.

Frequently asked questions
Can I use this as an accurate kitchen or trade scale?
No. It is a learning project and not a certified weighing instrument, so its accuracy depends on your calibration and should not be relied on for trade or safety use.
How do I calibrate the scale and use the tare button?
Place a known weight on the load cell and read the raw value from the HX711. Use it to set the scale factor in the code. The tare button resets the display to zero with the empty platform in place.
