【 摘 要 】

Today sensors are used in different fields especially in vehicle and aerospace industry. This paper presents the design and manufacturing of car engine's speed sensors. By using this system one can transfers engine's speed sensors data with high frequency to rev counter. This system works with radio wave transmitter. Electronic motor and choke produce analog waves and converter circuit converts these waves to digital waves and sends them to transmitter, so a receiver can get these pulses. This system was test in different conditions like rainy weather and for distance amount 80 meters. Advantages of this system are reduction in wires and car weight, accurate data transmission, and engine noise does not effect out put signals. By virtue of using oscillator and suitable circuit such as a divider when speed increases or decreases by 2 rpm, the change is observable, which is more precise comparing similar systems that have sensitivity of 2.15 rpm. Also due to use high frequency transmitter and receiver engine’s and environment’s noise doesn’t have any effect on data transferring.
