HX711 Load Cell Amplifier - 24-Bit ADC Module

Product Description

Achieve laboratory-grade precision in your weighing projects with the HX711 Weighing Pressure Sensor Module. This high-resolution 24-bit ADC is specifically designed for bridge-type sensors, making it the industry standard for interfacing load cells with microcontrollers. At Robogears, we recommend this "Big Size" version for its superior thermal stability and ease of use, as it comes with pre-soldered headers for immediate connection to your breadboard or PCB. The HX711 module simplifies the complex task of measuring tiny voltage changes from a load cell, converting them into a stable digital signal for your Pimpri workshop's automation and IoT scale projects.

Detailed Key Features

• 24-Bit High-Resolution ADC: Capable of detecting minute weight changes, allowing for the construction of scales that can measure from milligrams to hundreds of kilograms depending on the load cell used.

• Dual Differential Inputs: Features two programmable input channels, allowing you to monitor multiple load cells or bridge sensors simultaneously.

• Low Power Management: Includes an integrated power-on-reset and low-current standby mode, making it ideal for battery-operated portable scales.

• On-chip Low Noise Amplifier: Equipped with an active low-noise PGA with a selectable gain of 128, 64, or 32, ensuring a clean signal without external amplification.

• Professional Big Size Layout: The larger PCB footprint provides better heat dissipation and more space for secure wiring compared to mini versions.

All Technical Details

• Stability: On-chip oscillator requires no external components, reducing the overall footprint of your sensor array.

• Simplicity: Communicates via a simple two-wire serial interface (Clock and Data), compatible with any I/O pin on an Arduino or ESP32.

• Durability: Built with high-quality components to handle industrial environments and continuous monitoring tasks.

• Applications: Digital kitchen scales, industrial tension measurement, liquid level sensing, and automated inventory systems.
