Specifications

Key Features

• 24-Bit High-Resolution ADC: Captures extremely small voltage changes from load cells, enabling gram-level or even sub-gram accuracy in weight measurements.
• Programmable Gain Amplifier (PGA): Channel A supports gain of 128 (for full-bridge load cells) or 64, while Channel B offers gain of 32 for additional sensor inputs.
• Two Differential Input Channels: Connect a primary load cell on Channel A and a secondary sensor (such as a temperature compensation bridge) on Channel B simultaneously.
• Simple 2-Wire Digital Interface: Communicates using only DOUT (Data) and PD_SCK (Clock) pins-no complex SPI or I2C configuration required, making wiring and coding straightforward.
• On-Chip Voltage Regulator: Provides a stable, low-noise excitation voltage directly to the load cell from the module, eliminating the need for an external precision reference.
• Low Power Consumption: Draws under 1.5mA during normal operation with an automatic power-down mode (< 1uA) when the clock pin is held low.
• Selectable Output Data Rate: Choose 10 SPS for maximum noise rejection (50Hz and 60Hz simultaneous rejection) or 80 SPS for faster readings in dynamic applications.
• Wide Operating Voltage: Works reliably with both 3.3V and 5V logic microcontrollers, ensuring compatibility across virtually all development platforms.
• Compact Breakout Board Design: All necessary components pre-soldered on a small PCB with clearly labeled header pins for quick prototyping and clean integration.
• Extensive Library Support: Well-documented Arduino libraries (HX711 by Bogdan Necula, HX711_ADC by Olav Kallhovd) and MicroPython/CircuitPython drivers available for rapid development.

Why Choose the HX711 Module?

• Industry-Standard Load Cell Interface: The HX711 is the most widely used and well-documented load cell ADC in the maker and industrial prototyping community, ensuring abundant resources and community support.
• Exceptional Price-to-Performance Ratio: Delivers 24-bit precision comparable to expensive industrial signal conditioners at a fraction of the cost.
• 100% Authentic Components: Sourced directly from authorized distributors-genuine HX711 IC with verified specifications and reliable performance.
• Beginner-Friendly Implementation: Minimal external components needed; connect load cell wires, two digital pins to your microcontroller, and power-start reading weight data in minutes.
• 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India. Same-day delivery available in Bengaluru.
