high accuracy, ease of measurement and reliability. It will be easy for an indirect length sensing equipment to provide all the above quoted advantages. Here we present such a length measurement system to measure lengths between two points in a plane from a far off distance. This system consists of an ultrasonic distance sensor, potentiometer, servo motor, LASER and an LCD display. Here using the ultrasonic sensor, the distance between the plane containing the points and the instrument is measured. Now the angle made by the instrument between the two points is measured using a potentiometer. With the obtained values, the length between the points will be calculated using the program loaded to the Arduino board. Finally LCD displays the output. This work is practical and feasible according to the economic point of view and accuracy. The desired objective is highly accurate measurement of length between two points in a plane.
