Water quality and quantity monitoring based on ATmega328P microcontroller

The water quality and quantity monitoring system is designed to give an early warning detection of home water tank. The design of this project is based on ATmega328P microcontroller as the main controller for the whole system. The ultrasonic sensor and pH probe are used as inputs to the system. All the signal inputs from Ultrasonic sensor and pH probe will transmit to the microcontroller. The microcontroller will process the inputs and determine the consequence outputs. The LCD char 16x2 display, buzzer and the LEDs are used as output. The function of LCD display in this project is to display the remaining water level and also water quality continuously. The three LEDs are used as indicator in this project to indicate three stages water level at high level, medium level or low level. Lastly, a buzzer as an alarm and will activated when the water level at the lowest level. Basically, this system is designed to aid home owners in monitoring supply and safety of water tap in their home.
