HX711 Load Cell Weight Sensor Module 20kg with ADC for Electronic Scale

On-Chip Signal Conditioning for Accurate Weighing This load cell module combines a precision aluminium alloy weighing sensor with an integrated HX711 AD converter, delivering a complete solution for electronic scale projects. Available in this set as a 20kg capacity unit, it provides reliable weight measurement for a wide range of DIY and industrial applications. The module incorporates an on-chip power-on-reset function, ensuring stable start-up behaviour every time the system is powered. Two selectable differential input channels offer flexibility when configuring the sensor layout, allowing you to adapt the module to different load cell arrangements without additional external components. Integrated Low-Noise Amplification A key feature of this design is the on-chip active low-noise programmable gain amplifier, with selectable gains of 32, 64 and 128. This allows you to match the amplification level to your specific load cell output, improving resolution for lighter loads or accommodating higher-capacity sensors with ease. The result is a cleaner signal path that supports more consistent readings. Built-In Power Regulation The module also includes an on-chip power supply regulator dedicated to both the load cell and the ADC analogue power supply. This helps maintain a stable voltage reference during operation, reducing the risk of measurement drift caused by supply fluctuations. It simplifies your circuit design by removing the need for separate external regulation components. Practical Design for Electronic Scale Builds Constructed from aluminium alloy, the load cell offers a robust yet lightweight structure suitable for repeated use. The 20kg variant in this set is well suited to bench scales, kitchen scales, postal scales and other weighing devices where dependable performance is required. With the HX711 module handling signal conversion and conditioning, you can focus on the display and control elements of your project.
