1. A carbon monoxide (CO) leak alerting device comprising:
a CO measuring unit comprising a CO measurement sensor installed at a location corresponding to a boiler flue, the CO measuring unit being configured to measure and output a CO amount leaking from a boiler through the CO measurement sensor;
a collision detecting unit attached to the boiler flue and configured to detect a collision and an impact applied to the boiler flue and output a value of impact strength accordingly;
an alert alarm unit configured to issue an alarm; and
an alert controller configured to determine whether a CO leak is caused by separation of the boiler flue based on an impact on the boiler flue of the boiler through the collision detecting unit and a CO amount input to the CO measuring unit, and issue an alarm by controlling the alert alarm unit based on whether the CO leak is caused by the separation of the boiler flue.
