DESCRIPCIÓN DEL PRODUCTO
SparkFun Load Cell Amplifier - HX711 Read Load Cells to Measure Weight
About This Item
Introducing the SparkFun Load Cell Amplifier - HX711 Small Breakout Board: Your Solution for Accurate Weight Measurements! Whether you're a hobbyist or a professional, the SparkFun Load Cell Amplifier is the perfect tool for easily reading load cells to measure weight. With this small breakout board, you can connect the amplifier to your microcontroller and capture changes in the resistance of the load cell. With some calibration, you'll achieve highly accurate weight measurements. This versatile amplifier opens up a world of possibilities.
Use it to build your own industrial scale, implement process control in your projects, or even create a simple presence detection system. The SparkFun Load Cell Amplifier can handle it all. We've listened to your feedback and made some improvements to this version! The analog and digital supply have been separated, ensuring maximum performance. Additionally, we've included a 3.3uH inductor and a 0.1uF filter capacitor for digital supply, further enhancing signal quality. The HX711 IC, used by the amplifier, communicates through a two-wire interface (Clock and Data), making integration with any microcontroller a breeze.
Numerous libraries are available, simplifying the process of retrieving data from the HX711. Check out our hookup guide below for more details. Load cells are connected to the HX711 using a four-wire Wheatstone bridge configuration. The color-coded wires (RED, BLK, WHT, GRN, and YLW) correspond to standard load cell color coding.
Red represents Excitation+ or VCC, black represents Excitation- or GND, white represents Amplifier+, Signal+, or Output+, and green represents A-, S-, or O-. The yellow wire serves as an optional input for grounding and shielding against external electromagnetic interference (EMI). Please note that some load cells may have slight variations in color coding. Invest in the SparkFun Load Cell Amplifier - HX711 Small Breakout Board today and unlock the power of accurate weight measurement.
Whether you're a maker, engineer, or enthusiast, this amplifier is a must-have addition to your toolkit. Order now and take your projects to the next level!.
