HX711 24-Bit Load Cell Amplifier and Digital Display Module

The HX711 Intelligent Weighing Sensor Module combines a 24-bit analog-to-digital converter amplifier with an integrated 4-digit tube display for direct weight readouts. It features on-board buttons for zeroing, calibration, and tare functions without requiring a constant computer connection. This compact unit is ideal for makers, students, and engineers building electronic scales or mechanical strength testing rigs.

Integrated display and digital calibration

Equipped with four digital display tubes and a four-key interface, this module enables direct configuration, zero setting, peeling, and digital calibration on the fly. Parameters are saved to non-volatile memory, ensuring calibration values are retained after power loss.

Precision measurement and protection

The built-in HX711 chip provides a measurement signal range of ±19 mV with an adjustable acquisition speed of up to 100 Hz and high linearity. Integrated circuitry includes protection against reverse connection and overvoltage alongside instantaneous suppression.

Versatile connectivity and power

The module operates on a 5 V DC supply via a 3.5 mm power socket or Micro USB interface and supports up to four 350-ohm load cells. It can transmit data periodically or dynamically as weight measurements change.
