The small load cell amplifier is a breakout board for the HX711 IC makes it easy to read speed load cells to measure speed. Thanks to the combination of the amplifiers to change in your computer you can hang the resistance of the load cell to read and with some calibration youâll in an idea and are great precise weight measurements. This can be practically for making your own industrial scale, process control or simple presence detection function. HX711 uses a two wire interface (clock and data) that can be used for the communication. Everyone should Microcontrollerâs GPIO pins work and a multitude of libraries have been written, making it easy to reading of data from the HX711. Check the hookup below for more information. Load cells with a 4 Wheatstonesche gauge/wire to connect to the HX711. These are general color red, white, black, green, YLW. Each colour corresponds to the standard load cells Colour coding: Red: For Stimulating The + VCC)
