This HX711 24-bit precision ADC module is designed for high-precision electronic scales. It features two selectable differential input channels, making it ideal for weighing and pressure sensors that require high accuracy. The module integrates a low-noise programmable gain amplifier (PGA) with selectable gains of 32, 64, and 128, providing high-quality signal amplification. The input circuit can be configured to connect bridge-type sensors, making it a perfect solution for cost-effective and precise weight measurement. With an operation voltage range of 2.6V to 5.5V and low current consumption, it’s suitable for a wide range of applications in the electronic scale industry.
