✅ Product Description
The HX711 Sensor Module is a 24-bit dual-channel precision A/D converter specifically designed for weighing systems using load cells. It features the HX711 IC, allowing accurate analog-to-digital conversion for signals as low as a few millivolts. This compact and cost-effective breakout board is perfect for applications requiring high resolution and low noise, such as digital scales, force sensing, and precision weight measurement.
It integrates a programmable gain amplifier (PGA) and supports gains of 32, 64, and 128—ideal for amplifying signals from strain gauge-based load cells.
