HX711 LOAD CELL MODULE 

The HX711 Load Cell Module is a high-precision 24-bit analog-to-digital converter designed for load cell and weighing scale applications. It accurately measures minute resistance changes from strain gauge load cells and converts them into digital signals for microcontroller processing. With stable, low-noise, and high-resolution readings, this module is perfect for digital weighing scales, force measurement systems, industrial applications, and educational projects.

WORKING PRINCIPLE

Load cells contain strain gauges that change resistance when a force or weight is applied. The HX711 amplifies the small differential signal from the load cell and converts it into a 24-bit digital output. This digital data is then transmitted to a microcontroller via a simple two-wire interface (DATA and CLOCK), enabling precise weight and force measurements with ease.

TECHNICAL SPECIFICATIONS

The module uses the HX711 Weighing Sensor ADC and offers 24-bit resolution with differential load cell input. It operates within a voltage range of 2.6 V to 5.5 V DC and provides selectable gain options of 32, 64, or 128. Featuring a two-wire digital interface (DT and SCK) and sampling rates of 10 Hz or 80 Hz, the HX711 delivers low-noise, high-stability performance. It is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and PLC systems.

APPLICATIONS

Ideal for digital weighing scales, electronic balances, industrial and commercial weighing systems, and force or pressure measurement setups, the HX711 is also perfect for smart scales, IoT-enabled weight devices, and educational or DIY electronics projects. Compact, reliable, and easy to integrate, this module ensures accurate load and weight measurements for both practical and experimental use.
