Automatic sensing and switching the water pump: A new approach

In this paper, we introduce the design of an electronic system for automatic control of water pump motors that are used at homes to fill the overhead tanks with municipal water (piped water). The electric signals generated by the water flow sensor and water detector are feed to the microcontroller. Microcontroller process these detected signals to confirm whether water is present in the pipe and to calculate the water flow rate, to activate the relay that controls the switching of the water pump motor. The motor is switched ON if the water is detected in the pipe and its flow rate is greater than the critical flow rate if any one of the two conditions is not met then the motor is switched OFF. This work will be very helpful for people who rely on municipal water. As municipal water comes at random times in a day (in India), this work helps them to make their life easier.
