The 20 Kg Weight Sensor, also known as a load cell or strain gauge, is crafted from aluminum-alloy and is designed to accurately measure force in a single direction. It is capable of measuring up to 20 kg of force while disregarding other forces applied, focusing solely on the specific force being measured. This makes it suitable for applications such as small jewelry scales, kitchen scales, and various electronic weighing systems. It requires a load cell amplifier, such as the HX711 load cell amplifier or similar devices, to convert the mechanical force into an electrical signal output.
