In Automation era, a real time system needs an effective sensor design. Sensors act as a feedback unit of the control system, which provides measurable input from the environment. Individual sensors in the real time system are affected by the noisy environment which results in the production of messy output. So we go for soft sensor design. In autonomous vehicle, there is a need of gyro sensor, distance measuring sensor, and encoders to attain the desired target. The proposed project is to design the proximity sensor and Micro Electro Mechanical System motion sensor (Three axis digital output gyroscope) in Simulink by analyzing the real time datasheet of the corresponding sensors. These two sensors models are taken as systems in the form of transfer function. Then the outputs of these sensors are analyzed with the presence of noise and the signal is separated from the noise using FFT algorithm.
