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 electronic scales. Precautions: Mount one end of the sensor using the screw hole; leave the other end freely suspended. Apply force in the direction indicated by the label. Avoid touching the white epoxy-coated area to prevent damage. Simple digital control and serial interface: Pin-driven control, no programming required. Selectable output data rates: 10 SPS or 80 SPS. Load cell: Rugged aluminum alloy construction with strain gauge. Labels, appearance, and color may vary. No specific color or label requests accepted. Minor color variations between product and photo may occur due to lighting and display differences. This does not affect functionality. Color: As shown in photo Material: Metal Package Contents: 4 × Digital Load Cell Weight Sensors Note: Only the items listed above are included. Other accessories or components are not included. Measurement tolerance: ±1–3 cm.
