Simple operation: Maximum measuring force of the load cell: 5 kg (11 lb). Four leads. Easy to use—apply 5–10 V excitation voltage; force change is directly output as a voltage signal. Wiring method: Power positive (E+) – red, power negative (E–) – black, signal positive (S+) – green, signal negative (S–) – white. The HX711 module features a 24-bit high-precision A/D converter; it includes an integrated 128× programmable gain amplifier and two analog input channels, designed for high-precision weighing applications. Precautions: Mount one end of the sensor using the screw hole; keep the other end freely suspended. Apply force in the direction indicated by the label. Avoid pressing directly on the white epoxy-coated area to prevent damage. Simple digital control and serial interface: Pin-driven control—no programming required. Selectable output data rate: 10 SPS or 80 SPS. Load cell: Rugged aluminum alloy construction with strain gauge. Labels, appearance, and color may vary. No specific label, appearance, or color can be guaranteed. Minor color variation between product and photo is possible due to lighting and display differences. This does not affect functionality.
