Level sensor module and portable level measuring apparatus

A portable level measuring apparatus comprising:

• a sensor module having a sensor unit configured to measure an inclination of a measuring object and a first wireless communication unit configured to transmit a measured information that is measured at the sensor unit;
• and
• a portable terminal connected to the sensor module through a wireless communication, and configured to display the measured information,
• wherein the sensor module is configured to combine with the portable terminal through a connector and immediately pair with the portable terminal in response to being separated from the portable terminal,
• wherein the sensor module includes
• a built-in battery unit configured to supply a power source to the sensor unit and the first wireless communication unit;
• a charging unit configured to receive a charging power from the portable terminal for charging the built-in battery unit;
• and
• a control unit configured to control the first wireless communication unit to recognize a state in which a supply of the charging power is stopped by a separation of the charging unit from a charging terminal of the portable terminal, and configured to be wirelessly paired with the portable terminal,
• wherein the sensor unit, the first wireless communication unit, and the control unit are on a printed circuit substrate, and
• wherein the sensor module further comprises a flattened base substrate which has the printed circuit substrate on a top surface, and the sensor module is on a measured object.
