M5Stack Scale Kit w/ Weight Unit

Description M5Stack Scale Kit w/ Weight Unit Offers a high precision low-cost weighing kit Designed for high precision electronic scale Consists of four pieces of half-bridge resistive strain gauges Equipped with a 24-bit A/D converter chip Built-in low-noise programmable amplifier The M5Stack Scale Kit w/ Weight Unit 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 200 kg. 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 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 50 cm on one side.
