Blind Person Verification Using Temperature  Compensated Ultrasoni Ranging


Monika V. Chandak and Mr. Rajesh B. Pandhare



It contains a method to implement a mobility aid for blind person and also can be used in automatic robots, self-propelling vehicles in automated production factories etc. Model contains signal processing unit with PIC microcontroller which receives data from Ultrasonic sensor and Temperature sensor then processed it and delivers it to the computer using serial input/output port & gives alert to the blind person using voice processor with earphone. Paper contains temperature compensation method to reduce the error in measurement of distance using ultrasonic sensors. Signal processing unit contains PIC microcontroller which is used for interfacing between different sensors and computer. Then a MATLAB based calculation and analysis is carried out to obtain  the correct distance of the obstacle and to bring  out the difference in the measured value with  compensation and that without temperature compensation. The main advantage of this project is its simplicity and feasibility. In future the analysis can be done for different materials so that effect of all material can be analysed. Other factors such as humidity and pressure can also be included so that the combined compensation can reduce more error. Then received data is verified using MATLAB.
