HX711 Load Cell Amplifier Module

The module uses the HX711 as a controller, a 24-bit S/D converter chip specifically designed for digital scales. This module is used with one or two weight sensors, which provide a variable resistance depending on the weight.

With the HX711 Load Cell amplifier, you can easily read weight sensors to determine the weight. Since the differential signal from a weight sensor is very small, you cannot connect it directly to an Arduino, so you need to use this amplifier.

The HX711 module is equipped with a 24-bit ADC, allowing it to detect the smallest differences in weight. With the help of calibration weights, you could make a very accurate scale.
