Automatic Water Level Controller

• The one described here is built around timer NE555 and inverter buffer CMOS IC CD4049.
• It uses readily-available, low-cost components, and is easy to build and install on the over-head tank (OHT) to prevent wastage of water.
• The circuit works off a 12V battery or 230V AC mains using a 12V adaptor.
• The three sensors built from non-corrosive metal are fitted to the over head tank to prevent wastage.
• As water is consumed and its level falls below sensor,the motor restart.
• Also can manually start and stop motor using switch.
