| Abstract: | The designing idea and realization method of a wireless tachometer of the engine with the wireless transmission technique were discussed. The design of the hardware and software of the wireless tachometer system was provided, based on TX100/RX100 ASK wireless receiving and transmitting radio module, real time clock chip PCF8563, AT89C2051 microcomputer and four-bit serial segmentary LCD of EDM1190A. The tachometer can be used to measure the rotational speed of engine and display time. After experimentation, the result shows that the performance of the system is stable and can be used conveniently and reliably. |
