The Gravity HX711 Load Cell / Wheatstone Bridge Interface is based on HX711, which is a precision 24-bit analog-to-digital convertor designed for weight scale and industrial control applications to interface directly with a bridge sensor. It not only has a few basic functions, but also contains high integration, fast response, immunity, and other features.
This weight sensor lowers the cost of the electronic scale, and at the same time improving the performance and reliability. The input interface is compatible with Arduino I/O port. The output adopts compact terminal that makes the sensor easier to connect.
