## Description

A digital weight sensor kit based on the HX711 24-bit ADC, capable of measuring up to 1 kg. The HX711 is designed specifically for weight scale applications, interfacing directly with a bridge sensor to deliver precise, reliable measurements via the Gravity interface. The kit includes both the HX711 weight sensor module and a 1 kg load cell, making it easy to build a digital scale for home, laboratory, or industrial use with Arduino and other microcontrollers. Key Features HX711 24-Bit ADC – High-precision analog-to-digital converter for weight scales 1 kg Range – Suitable for small-scale weighing applications Selectable Gain – PGA with 32, 64, and 128 gain settings Selectable Data Rate – 10 SPS or 80 SPS output Wide Supply Voltage – 2.6–5.5V Low Current – Less than 1.6 mA Gravity Interface – Simple plug-and-play connection Weight Sensor Specifications Range – 1 kg Excitation Voltage – 5–15V Output Sensitivity – 1.0 ±0.15 mV/V Input Impedance – 1055 ±15 Ω Output Impedance – 1000 ±5 Ω Overload Capability – 200% F.S. Module Size – 33 × 38 mm Wiring Red – E+ Black – E- White – S- Green – S+ Package Contents 1× Weight Sensor Module (HX711) 1× Weight Sensor (1 kg load cell) 2× Sensor Cables Resources Product Wiki HX711 Datasheet (PDF) Schematic (PDF) Arduino Library (ZIP) 3D Printed Module Design Files
