Simple operation: the maximum measuring force of the load cell is 5kg (11lb), with four leads for easy use. Apply 5-10V excitation voltage, and the force change is directly output as a voltage signal. Wiring: 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 conversion chip; the HX711 includes a built-in 128x programmable gain amplifier and is designed for high-precision electronic scales with two analog input channels. Precautions: One end of the sensor should be fixed using the screw hole, while the other end remains suspended, loaded in the direction indicated by the label. Avoid pressing the white epoxy-coated area to prevent sensor damage. Simple digital control and serial interface: pin-driven control, no programming required, with selectable 10SPS or 80SPS output data rate. LOAD CELL - Constructed from durable aluminum alloy with strain gauge technology. Note: Labels, appearance, and colors may vary randomly; specific styles or colors cannot be selected.
