The HKD A/D Weighing Sensor Converter Module is built around the HX711 24-bit precision A/D converter, designed for weight and pressure sensor applications. Featuring dual-channel differential inputs, low-noise programmable gain (32, 64, 128), and excellent anti-interference performance with its metal shielding, this module is widely used in digital scales and weighing systems. The onboard voltage regulation and oscillator ensure stable operation without requiring external components. With an optional MCU (STC15F104) position for secondary development and compatibility with Arduino and other microcontrollers, this module is ideal for DIY weighing projects, robotics, and industrial applications.
