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 output as a proportional 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 provided 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. Digital 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 technology. Appearance, color, and labeling may vary; no specific color or label can be guaranteed. Minor color variations between product photos and physical item may occur due to lighting and screen settings. These do not affect functionality. Color: As shown in photo Material: Metal Package Contents: 4 × Digital Load Cell Weight Sensors Note: Other accessories or items shown are not included. Measurement tolerance: ±1–3 cm.
