【摘要】 介绍一种基于nRF2401的汽车发动机转速遥测系统。采用外夹式传感器采集汽车发动机转速信息,进行整形,通过nRF2401进行数据传输,接收后利用单片机AT89C2051进行频率变换并驱动液晶显示结果。由于nRF2401具有高传输速率,因此最终实现了汽车发动机的转速遥测。更多还原

【Abstract】 A kind of telemetering system for the rotative speed of motor engines based on nRF2401 was introduced.The outside-nipped sensor was used to collect the rotative speed information of motor engines.The signals were then shaped,after which they were transmitted by nRF2401.Frequency conversion and the drive of the LCD will be implemented by AT89C2051.As nRF2401 is a high-speed wireless transceiver chip,the system finally can realize the telemetering of rotative speed of motor engines.更多还原
