Description
The HX711 Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily 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, and with some calibration, you’ll be able to get very accurate weight measurements simply it amplifies the small signals that come from the load cell. This can be handy for creating your own industrial scale, process control or simple presence detection.
Load cells use a four wire Wheatstone bridge to connect to the HX711.
