Provided is a functional float capable of measuring a temperature and the depth of water. To this end, the functional float comprises: a buoyancy part having a space formed therein so as to have buoyance and further including a nut groove part at a lower part; a weight part having a specific mass and made of ceramic; a water depth measuring unit formed in the buoyance part and allowing fluid to flow therein; a water temperature gauge; and a light-emitting part including a light emitting diode (LED) lamp so as to check the water temperature gauge and a water depth measuring pipe at night. |
