This paper proposes the prototype of a wave maker for Laboratory Environment. The conceptual design is presented to describe the working principle of the proposed wave maker. Here, a slider crank mechanism is employed to converts continuous rotary motion of a disc into harmonic reciprocating motion on the vertical axis. A curved plate fixed to the end of the crank is forced to move up and down directions. Then, the curved metal force water surface to move forward and backward direction. These motions create the wave form. Moreover, the wave with different amplitude and frequencies is made by changing the crank position and angular velocity of the electric motor. The disc has predrilled hole in some specific positions, so that the end of the crank could be fixed in different position for the distinct waves. A servo motor is employed to change the frequency of the actuator. Finally, an ultrasonic sensor is utilized as an output data in order to verify the water level and wave height. The generated waves can be applied to study in the Laboratory environment.
