Abstract:
This project is to develop a water purifier that is driven by solar energy and may be
utilised for an infinite amount oftime, with the quality of the water being monitored
automatically by means of sensors. The concept of reverse osmosis serves as the
driving force behind this endeavour. The solar panel is responsible for absorbing the
sun's rays. After then, this energy is stored in a battery, which also serves to regulate
it. The battery is connected to the inverter and the dc connection port, which is the
location from where the purifying unit runs, through a switch. The purification unit
features a pressure-maintained pump and a reverse osmosis system as part of its
components. A high-pressure pump is used to provide the pressure necessary for the
process ofreverse osmosis. The microcontroller examines both pure and non-purifled
water with a pH sensor and a Tds sensor, depending on the type ofwater, to determine
whether or not it is healthy to consume. With these sensors, we are able to determine
the PH (potential hydrogen ion) as well as the TDS (parts per million) of water (input
and output). We are able to determine whether the water is safe to drink through the
automation of these sensors, and if it is not, we are able to re-purify the water down
the drain. After carrying out this method, both the water tank and the output tap will
be supplied with water that has been cleaned and disinfected.
