DFRobot Gravity: Digital Weight Sensor | SEN0160

This Electronic Arduino Weight Sensor is able to detect 1kg weight. It based on HX711, a precision 24-bit analog-to-digital converter designed for weight scale and industrial control applications to interface directly with a bridge sensor.

This Electronic arduino weight sensor lowers the cost of the electronic scale, and at the same time improving the performance and reliability. The interface of this sensor uses DFRobot Gravity Interface. The output adopts compact terminal that makes the sensor easier to connect. It's the best choose for electronic enthusiast to do some tiny home scale.
