Unit Scales
SKU:U108
Description
Unit Scales is a 20 kg integrated weighing sensor unit with an I2C interface. It integrates an STM32F030 microcontroller, acquisition circuit, and a 20 kg weighing sensor internally. The unit uses the HX711 dedicated weighing acquisition chip, features a tare button, and a programmable RGB status indicator. Users can read weight data via the I2C interface. This unit provides a highly integrated weighing detection solution, suitable for applications such as quality inspection, piece counting, and object movement detection.
