The real-time water quality monitoring and notification system (water QMS) measures the essential qualities of water -- the water PH, temperature, turbidity (cloudiness of water), and water level in the tank -- in real time. The system consists of multiple sensors to measure the standards of water in the tank, the micro-controller to analyze the readings and the GSM module to send the information to the watching centre through SMS. It is a true time system, which is able to measure the standards of water endlessly, and can send the measured values to the watching centre when each predefined time. I developed the device to allow people to have access to safe water in their daily life.
