SparkFun Load Cell Amplifier – HX711
SparkFun Load Cell Amplifier - HX711
This small load cell amplifier is a breakout board for the HX711 IC that lets you easily read load cells to measure. By connecting the amplifier to your computer you can read the changes in the resistance of the load cell and with some calibration you can make very accurate weight measurements. This can be practical for designing your own industrial scale, process control or simple presence detection. HX711 uses a two-wire interface (clock and data) for communication. Each microcontroller's GPIO pins work and numerous libraries have been written, making it easy to read data from the HX711. Check the Hookup below for more information. Load cells with a 4 wire Wheatstone measuring bridge to connect to the HX711. These are generally color red, white, black, green, YLW. Each color corresponds to the traditional color marking of the load cells: red: excitation, the + VCC)
