摘要：Ultrasonic are one of the most popular technique used by industries to test and evaluate their product called non-destructive testing (NDT). This paper presents the design of a model water quality measurement using sound signal. The model is preliminary action to measure time travel of sound wave in water. Ultrasonic will transmit and receive the sound signal by with 42 KHz frequency operation. Data received by ArduinoMega and at the same time send to the smartphone using HC05 Bluetooth module. Measurement of water located at Klang River where most of factories are located near to it. The time of flight (ToF) from the sensor are recorded, analyzed and presented in result.
