The HX711 load cell amplifier is a small breakout board for the HX711 IC that allows you to read load cells to measure weight. By connecting the amplifier to your microcontroller, you will be able to read the changes in the resistance of the load cell, & with some calibration, you'll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presense detection. The HX711 uses a two-wire interface (clock & data) for communication. Any microconotrller's GPIO pins should work, & numerous libraries have been written, making it easy to read data from the HX711.
