• Comes with a booklet (with assembly and wiring diagrams, code), video and web page tutorial are provided to guide you step by step on how to build(scan the QR code to get them)
• HX711 is a chip of 24 bit A\D converter designed for high precision weighing sensor, can directly supply power for external sensor and A\D converter, with automatic reset function
• Has beautiful package and Rohs & FCC certification, all components are made from from environmentally friendly material and technology, they are safe and in good quality
• This diy weight scale is a great electricity science kits for education, provides a great platform to develop your coding skills and allow you complete a variety of interesting experiments

<b>Principle </b><br> Electronic scale weigh force according to slight deformation causing by pressing metal. It uses the most commonly used strain gauge to measure deformation. In a typical application, utilize the <br>strain gauge adhered on face of this sensor, to measure the force bore by the sensor. <br> <br> <b>HX711 Chip </b><br> HX711 is featured with high integration, quick response and strong anti-interference, integrated external circuit needed by other chips including stabilized voltage supply and on-chip clock <br>oscillator. It decreases cost of complete machine of the scale, and in the same time improve its performance and reliability. <br> <b>Features </b><br> Channel A or B can choose different input. <br> The gain is 64 or 128 in the low-noise programmable amplifier. <br> Stabilized voltage supply offered by chip can directly supply power for external sensor and A\D converter. <br> Clock oscillator doesn't need any external device. If necessary, it can use external crystal oscillator or clock. <br> Automatic reset function <br> All control signals are driven by pins, without programming register of inner chip. <br> Alternative 10Hz or 80Hz of output data rate <br> <br> <b>DIY Electronic Weighing Scale Kit List: </b><br> keyestudio R3 Development Board 1 <br> I2C 1602 LCD1 <br> keyestudio Digital Push Button1 <br> keyestudio HX711 Weighing Module1 <br> 5KG Rheostat Sensor1 <br> Tabula Board（Upper Board）1 <br> Tabula Board（Bottom Board）1 <br> keyestudio R=120mm Bearing Acrylic Board1 <br> keyestudio 15*11*4 Acrylic Board 4mm Spacer1 <br> 50g Weight1 <br> 100g Weight1 <br> Self-adhesion 3M Crashproof Transparent Colloidal Particle∮10*5（4 Granules）1 <br> M3*6MM Round Head Screw23 <br> M3 Nickeling Nut2 <br> M4*10MM Round Head Screw2 <br> Hexagonal Copper Fistular M3*10MM8 <br> Hexagonal Copper Fistular M3*40MM1 <br> Female to Female Dupont Line15CM20 <br> USB Cable1 <br> 18650 Battery Case <br>
