The Grove – ADC for Load Cell (HX711) is a 24-bit A/D converter designed specifically for the load cells we sell. It contains an on-chip low noise programmable amplifier with an optional gain of 32, 64 and 128. The HX711 chip integrates a regulated power supply, an on-chip clock oscillator, and other peripheral circuits, which have the advantages of high integration, fast response, and strong anti-interference.

With the Grove connector and 4-pin screw terminal, it becomes quite easy to connect the load cell and microcontroller, no soldering required. You can build your own Arduino weight sensor system in just a few simple steps.
