Design & Imlementation of Smart RO Purifier for Remote Monitoring using IoT Sensor

There are some major deficiencies in existing models of modern water purifiers such as when water purification motor runs in spite of having no water inlet results in burning of the motor circuit. The first module of the invention solves this problem by checking the flow of water inlet using Water Flow Sensor and sends signal to user’s smartphone when water flow anyhow stops. User can then cut power flowing to the motor. This will also prevent the wastage of electricity that is going to be used by the motor. Now, in almost every purifier, the purifying device runs on its own and have fixed parameter of water level on which it runs. But it results in wastage of electricity and potential of purifier. So, this invention will use ultrasonic sensor that calculates the water level and user can dynamically set the water level parameter on which the purifier will run. And in normal purifiers, we get the fixed water purifying rate and speed which does not vary on the basis of water quality and ultimately reduce the performance level of the purifier. Therefore, this invention will use a smart regulator connected with our mobile device through cloud and by which user can control the purifier’s rate and speed according to the water quality. Smart water purifier is equipped with a Water Flow Sensor which will check the flow of water through inlet, an Ultrasonic Sensor which measures the level of water purified by the purifier, a pH-rod to check the quality of water and a $16 \times 2$ LCD Module to display the readings of the sensors.
