Scale Kit with Weight Unit

Description

The Scales Kit is an electronic scale kit that uses four sets of half-bridge resistive strain gauges, with a total weighing capacity of up to 200kg. It is paired with a high-precision 24-bit A/D converter chip, the HX711, which features a built-in low-noise programmable amplifier supporting gain adjustments of 32, 64, and 128. When combined with the M5Stack main controller, it allows for the quick and easy construction of an IoT weighing application in just a few minutes.
