LASER GUIDED DIGITAL FLOOD GAUGE
ABSTRACT It works on the principle of time of flight, when a laser beam is subjected to an object it used to find the range of
an object by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be
reflected off the target and returned to the sender, The returned pulse is calculated in terms of measuring signals. The
project laser guided digital flood gauge is a device which used to find water level or flood level in the dam by fixing sliding
floater in a dam water parallel to laser range finding sensor at a certain distance and measuring values are calibrated in
microcontroller basing on normal water level of dam, so that raise and fall of water level in dam is measured in the form
laser pulse signals later which is sent to the microcontroller then signals are converted into measuring values and will be
indicated on a digital indicating display.
Keywords: Time of flight, Sliding floater, Laser range finding sensor, Digital indicating display.
