The main purpose of this project is to control the dam shutter automatically. The main purpose behind adding the level scanning section is to avoid malfunctioning of the receiver section due to power failure (as no battery is added to the receiver to latch the present level of the dam water). In case we add a battery and the power fails , the water level is latched but during this period if the water level goes bellow any probe , there is no way to transmit the signal from the transmitter . This levels us with no other option but to add level scanning section. When power resumes, the level scanning section scans and chec!s all the levels one by one (from empty to full) and transmits the corresponding codes to the receiver to show the water level in the dam
