PURPOSE: A smart water play device is provided to use a piezoelectric material or manufacture a mechanical foot keyboard, thereby changing the height of a water pillar or the color of water according to the location of the foot keyboard and pressing strength. CONSTITUTION: A smart water play device includes a support stand, a jetting nozzle(120), a human sensor(130), a location sensor, and an MCU. The support stand is fixed to the ground. The jetting nozzle is formed on the support stand. Water is jetted by rotating the jetting nozzle. The human senor is formed on the support stand to sense a human body. The location sensor is formed on the support stand to sense the location of the human body. The MCU controls the jetting nozzle according to whether the human body exists or the location of the human body to jet water. |
