Distance measurement is required in every field. Generally there are two methods for distance measurement contact and non-contact. A non-contact method using ultrasonic sensor is described in this paper. Ultrasonic transducer uses the time of flight technique for distance measurement. This circuit calculates the time interval between the transmitted and reflected signal which is further evaluated for distance measurement. It has been tested successfully for measuring distance of an object up to 5m and corresponding area and volume has been calculated.
