Description: 1. The HX711 Load Cell Module is a microcontroller-based amplifier designed specifically for interfacing with industrial load cells to measure weight or force in IoT applications. 2. It features a high input impedance, allowing it to interface directly with most types of strain gauge bridge load cells without the need for external sensors or signal conditioning circuits. 3. This module employs an internal 24-bit ADC with a resolution of up to 14 bits, providing accurate and reliable weight measurements, and the data can be read via I²C communication interface. 4. The HX711 Load Cell Module supports automatic zero tare functionality, which eliminates the need for manual calibration and ensures consistent measurement accuracy over time. 5. It offers flexible gain settings (selectable via an external resistor) to accommodate various load cell types and output ranges, ensuring compatibility with a broad range of industrial applications. 6. The module's small size and low power consum
