Description Simple operation: the maximum measuring force of the load cell: 5kg (11lb), four leads, easy to use, add 5-10V driving voltage, the 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 adopts a 24-bit high-precision A/D conversion chip hx711; HX711 is an internal integrated 128-fold programmable gain amplifier with two analog input channels designed for high-precision electronic scales Precautions: One end of the sensor is fixed through the screw hole, and the other end is in a suspended state, and is applied in the direction indicated by the label. Special attention must be paid not to directly the white glue-coated part, so as not to damage the sensor Simple digital control and serial interface: pin drive control, no programming required, selectable 10SPS or 80SPS output data rate. LOAD CELL - Rugged aluminum alloy construction with strain The labels are random,the appearance and color are random, dont accept the specified Please note: the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!
