Gravity: I2C 1Kg Weight Sensor Kit - HX711 (Full Kit with Acrylic Base, Ready-to-use)

The Gravity I2C 1Kg Weight Sensor Kit provides a complete, easy-to-assemble electronic weighing solution with a load cell, signal processing board, and acrylic hardware. Featuring a built-in calibration algorithm and an onboard MCU, it is ideal for students, educators, and makers building smart scales and IoT monitoring projects without complex calibration routines.

Ready-to-assemble scale platform

The kit includes a pre-cut acrylic base and all necessary mounting hardware, allowing you to construct a complete working scale in minutes. It eliminates the need for soldering or fabricating custom structural parts.

Onboard MCU and one-key calibration

An onboard microcontroller processes the HX711 signal and handles calibration internally. You can calibrate the sensor instantly using a physical button press or directly through software API commands.

Gravity I2C interface and cross-platform support

The signal adapter communicates over standard I2C with selectable addresses from 0x64 to 0x67. It operates at 3.3V to 5V and works seamlessly with Arduino, micro:bit, ESP32, and Raspberry Pi boards.

Precision measurement performance

The load cell measures weights from 1g to 1000g with a synthesis deviation of less than ±0.2% g. Operating current remains below 20mA, making it suitable for low-power and IoT weighing platforms.

Complete hardware package

The pack contains the 1kg weight sensor, signal transfer board, acrylic bracket, trapezoidal rubber feet, mounting screws, nuts, and a 4-pin Gravity I2C connection cable.
