The M5Stack Scales Kit is a high precision low-cost weighing kit. This digital Scales kit is consist of four pieces of half-bridge resistive strain gauges, with a total weighing range of 200kgs. It is equipped with a 24-bit A/D converter chip HX711, specially designed for the high precision electronic scale. The built-in low-noise programmable amplifier supports 32/64/128 times gain adjustment. With the help of an M5Stack core for programming, you can create IoT based weighing scale in just a few minutes! Note: The Scale Kit will need a cover plate to work with, and the size of the cover plate should not exceed 50cm on one side.
