Levelling is a branch of surveying to find the elevations of given points with respect to a datum and to establish the points. The existing instrument consists of a telescope through which the leveling staff can be focused and the readings are taken manually. Since the readings are seen through telescope upside down and the readings are noted in the field manually, if any mistake is noted in the office, the whole instrument is again to be taken to the field to redo the work. Besides, this instrument is complicated and heavy. Hence, a new electronic level indicator is invented using transmitter and sensors. The proposed level consists of a transmitter to pass light ray on the leveling staff which is embedded with sensors to communicate the reading to the digital display. The readings are stored and transmitted to the office system simultaneously. This level is handy and cheap when compared to existing electronic level.
