5V Electronic Scale DIY Kit 1KG Weighing Capacity 51 Microcontroller Solder Practice Kit HX711 Chip with Digital Tube Display

Features:1. DIY electronic scale kit based on the 51 microcontroller, ideal for soldering practice and learning.2. High-precision measurement with 0.01g resolution (G mode) and 1KG capacity.3. Digital display shows weight, supports G/KG unit switching for easy operation.4. Features tare and fine-tuning calibration functions to enhance measurement accuracy.5. Automatic overload alarm. Compact design with finished dimensions of only 85mm diameter × 43mm height.Product Specifications:Supply Voltage: DC 5VProduct Dimensions: 85mm diameter × 43mm heightMaximum Capacity: 1KGFunctions:1. Digital display shows detected weight, with switchable units (g/kg);2. Fine-tuning calibration function ensures more accurate measurement data;3. Resolution: 0.01g when unit is g, 1g when unit is kg;4. Tare function;5: Alarms when object exceeds measurement range;Working Principle: Utilizes STC15W408S microcontroller as main controller, HX711 weighing-specific AD chip for data sampling, and LED display for weight indication; four side-mounted tactile buttons serve as human-machine interface;Usage Guide:1) After soldering the finished product, plug in the power supply and press the switch. The LED lights up and the buzzer sounds for several seconds. The LED display shows 0.000, with the unit in KG, minimum scale division of g, and a capacity of 1KG. The buzzer will alarm if the weight exceeds 1KG;(2) Place the electronic scale on a level surface and press the tare button to reset to zero;(3) Press the unit switch button. The display shows 00.00, indicating grams (g) as the unit. The minimum division is 0.01g, and the maximum capacity is 99.99g. If the weight exceeds capacity, the buzzer will sound. Press the unit switch button again to switch to kilograms (KG), and the buzzer will stop sounding;(4) Features a memory fine-tuning function. For example, when weighing a 100g object and the display shows 98g, press the Fine-Tune+ button to adjust to 100g for enhanced accuracy. Conversely, press Fine-Tune- to decrease the weight.(5) The Zero Reset button can be used for tare weighing.Product List:1X Electronic Scale DIY Kit
