【Abstract】 This method is different from the traditional detection speed,a new design idea in the detection of metal gear speed is proposed,which takes the LDC1000 digital inductance sensor as the core,and the low cost MSP430F149 chip as the control core.The homemade inductance coil is used to complete the speed measurement.The RF transceiver chip nRF24L01 is used as a speed information data transmission device which has a good prospect.The theoretical basis of speed measurement is analyzed,and the circuit schematic diagram and program flow chart are given.The system achieves the speed measurement of metal gear and the sharing of data transmission.更多还原
