Description

The HX711 Digital Weight Sensor Module is an A/D converter designed to interface with load cell sensors to provide accurate weight and pressure measurements. With a 24-bit resolution, the module converts the analog signal from the load cell into a digital signal for precise, reliable data output. Ideal for industrial weighing systems, tensile testing machines, and process control, this module offers strong anti-interference protection and easy parameter setting with a 4-key interface, making it a versatile solution for weighing applications.
