This paper presents a sensor of steering wheel rotation angel, taking the absolutely photoelectric encoder at the core component. The key point is to give a way to achieve the hardware and software of this rotation angle sensor. The sensor get the wheel rotation angle by the photoelectric encoder,and the MCU converts the receiving electric signal from encoder into angle values,then other moderns can share these values through CAN bus. By contrast experiments,the analysis shows the sensor advantages of high measurement accuracy,simple structure,strong ability of anti-interference.
