PURPOSE: A smart-ball for detecting the leak of water at water pipes buried in ground is provided to accurately detect a water leaking point due to cracks of pipes. CONSTITUTION: A smart-ball for detecting the leak of water at water pipes comprises a main body, a camera, a lighting device, a microphone gyro sensor, an acceleration sensor, a CPU, a memory. The camera takes a picture of exterior of a body in a radial direction. The lighting device is installed inside the body and emits light to the picturing direction of camera. The microphone is installed inside the body and changes a sound signal of the inner pipe into a digital signal. CPU synchronizes the data, transmitted from the camera, microphone, gyro sensor and acceleration sensor, to the time or distance. The memory stores data processed by CPU.
