Microcontroller electronic scale kit with stand. Load cell circuit. Experimental components. Self-assembled circuit board. Easy.

The electronic scale is primarily controlled by the STC90C52RC microcontroller, which handles the basic control functions.The system extends the functionality of the electronic calendar clock. It can be divided into six components: the system itself, data acquisition, the human-machine interface, the power supply, the clock, and voice output.The system essentially consists of the STC90C52RC and a standard reset circuit. Data acquisition includes a weighing sensor, signal amplification, and analog-to-digital conversion (ADC). Signal amplification and ADC are primarily percompatible withmed by the high-precision 24-bit HX711 ADC.The human-machine interface consists of a keypad and a dot-matrix LCD display. A 4x4 matrix keypad and a 1602 LCD are primarily used compatible with convenient data entry and intuitive display.The electronic scale offers basic weighing functions (weighing range 0–3 kg, maximum weight error ±0.005 kg) and also features a clock and voice output. The clock module allows you to set an alarm. The system will warn you if the weighing range is exceeded.Color: As shownMaterial: PlasticDue to different production batches, the appearance may vary, but this does not affect the functionality.Package Contents:1 x Microcontroller Electronic Scale (DIY Kit)Only the above package contents are included. Other products are not included.Note: Light reflections and different screen settings may cause the color of the item in the picture to differ slightly from the original. The measurement deviation is +/- 1–3 cm.
