DescriptionThis Arduino-based electronic weight sensor is capable of detecting a weight of up to 1kg. It uses a precision 24-bit analog-to-digital converter called HX711, which is designed for weight scale and industrial control applications, to interface directly with a bridge sensor. This electronic Arduino weight sensor is not only cost-effective but also offers improved performance and reliability. It uses the DFRobot Gravity Interface for easy connection and has a compact terminal for output. It’s an excellent choice for electronic enthusiasts who want to create their small home scale.Sensor connection Note：Red Line — E Black Line — E-White Line — S-Green Line — S SPECIFICATION24-bit Analog-to-Digital Converter for Weight Scales (HX711)Two selectable differential input channelsOn-chip active low noise PGA with selectable gain of 32,64 and 128On-chip power supply regulator for load-cell and ADC analog power supplyOn-chip oscillator requiring no external component with optional external crystalOn-chip power-on-restSimple digital control and serial interface: pin-driven controls, no programming neededSelectable 10SPS or 80SPS output data rateSimultaneous 50 and 60-supply rejectionSupply Voltage: 2.6V~5.5VCurrent: <1.6mAWorking temperature: -40~85°C16-pin SOP-16 packageWeight Sensor ModuleRange: 1kgExcitation voltage: 5-15 VOutput sensitivity: 1.0±0.15mV/VSynthetical error: 1 per thousand per cent of full-scaleZero shift: 0.05/0.03 （30min）%F.SZero temperature shift: 0.05/0.03 %F.S/10°CZero output: ±0.1mV/VInput impedance: 1055±15 ΩOutput impedance: 1000±5 ΩOverload capability: 200 %F.SOutput: Analog outputSize: 33mm*38mmDOCUMENTSWIKI (Weight Sensor Module SKU:SEN0160) libraryschematicdatasheet3D printed module design filesSHIPPING LIST1 x Weight sensor module1 x Weight sensor1 x Sensor cable
