HX711 Load Cell Module

HX711 Load Cell Module

The HX711 Load Cell Module is a high-precision 24-bit ADC designed for weight measurement applications. It is widely used with load cells to build digital scales and other force-sensing projects. With its built-in amplifier and easy two-wire interface (Clock and Data), this module allows microcontrollers to read weight values with exceptional accuracy and minimal effort.

Ideal for DIY electronic scales, smart weighing systems, industrial automation, and process monitoring, the HX711 ensures reliable performance in compact projects. The module directly interfaces with load cells that use a four-wire Wheatstone bridge configuration, making setup straightforward and efficient.
