HX711

Product Introduction

HX711 is a chip specifically designed for small-scale weight measurement. It has a built-in voltage gain and ADC module, which can detect voltage changes at the millivolt level. When paired with a electric bridge device composed of a pressure sensing plate, it can measure weight. Its features are as follows:
1.Low power consumption, enabling battery-powered operation.
2.High accuracy， The built-in high-precision gain amplifier avoids external electromagnetic interference, with an error of less than 0.1%.
3.Compact and lightweight, allowing for arbitrary concealment, and there is no difficulty in customizing the shell.
