## Description

The Gravity I2C 1 kg Weight Sensor Kit is a complete scale-building kit that includes a load cell, HX711 signal adapter board, acrylic mounting bracket, and all hardware needed to measure weight from 1 g to 1,000 g. The on-board MCU processes HX711 data and communicates via I²C, making it compatible with Arduino, micro:bit, ESP32, and Raspberry Pi. Unlike basic HX711 breakouts, this kit features a built-in calibration algorithm with one-button calibration — no separate calibration sketch needed. Simply press the button or use the API to calibrate, then start reading weight values over I²C. Key Features 1 g to 1,000 g Range – Suitable for small-scale weighing applications HX711 ADC with On-board MCU – Processed data output via I²C for easy integration One-Button Calibration – Built-in calibration algorithm, no separate code needed API Calibration – Alternatively calibrate programmatically via software Gravity I²C Interface – Standard DFRobot Gravity connector with 3.3V/5V compatibility Configurable I²C Address – 0x64, 0x65, 0x66, or 0x67 Complete Kit – All mounting hardware and acrylic bracket included Specifications Measuring Range: 1 g – 1,000 g Working Voltage: 3.3V / 5V Working Current: <20 mA AD Conversion Chip: HX711 Communication: I²C Signal Board Size: 31 × 37 mm Assembled Dimensions: 120 × 100 × 30 mm Compatibility Arduino (Uno, Mega, Leonardo, etc.) micro:bit ESP32 Raspberry Pi Ideal For DIY electronic scales Inventory and supply-level monitoring IoT weighing platforms STEM education projects Package Contents 1× Weight sensor (load cell) 1× Signal transfer board (HX711 + MCU) 1× Acrylic bracket 2× M4×20 screws 2× M5×20 screws 2× M3×8 screws and nuts 4× Trapezoidal feet 1× Gravity 4-pin I²C cable Resources Product Wiki (Documentation, Code Examples, Assembly Guide)
