This Weight Sensor amplifier is based on HX711, which consists of an amplifier and a precision 24-bit analog-to-digital convertor designed for weigh scale and industrial control applications to interface directly with a bridge sensor. Compared with other chips, HX711 not only has a few basic functions, but also contains high integration, fast response, immunity, and other features. The chip lowered the cost of the electronic scale, at the same time, improving the performance and reliability. The input interface of this weight sensor module uses a sensor interface, which is compatible with Arduino I/O ports. The output adopts a compact terminal that makes the weight sensor module to connect the weight sensor. It's the best choice for electronic enthusiasts to do some tiny home scale.
Some load cells we have that can be used with the HX711:
