Grove - ADC for Load Cell (HX711)
The Grove - ADC for Load Cell is designed to save you time and effort by making it easy to use load cells.
The Grove - ADC for Load Cell (HX711) is a 24-bit A/D converter designed specifically for the load cell. 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, with no soldering required. You can build your own Arduino weight sensor system in just a few simple steps.
NOTE: Channel A is for weight measurement, it has a programmable gain of 128 or 64. Channel B is used for system parameter detection, it has a fixed 32 gain
- Working voltage: 2.6V--5.5V (Note: The module measurement accuracy is related to the supply voltage. The higher the voltage, the higher the accuracy.)
- Working current: <1.5mA
- Detection accuracy: 24 bits
- Optional 10SPS or 80SPS output data rate
- Optional gain: 32 for Channel B / 64 and 128 for Channel A
