PURPOSE: A cigarette smoke sensing module, a cigarette smoke sensing device having the same, and a cigarette smoke sensing method are provided to complexly sense cigarette smoke with a plurality of sensors, thereby reducing malfunction rate.;CONSTITUTION: A cigarette smoke sensing module(10) comprises first and second sensors and a microcontroller unit(14). The first and second sensors sense cigarette smoke. The micro controller unit compares the first concentration of the cigarette smoke sensed by the first sensor and a preset a first-1 critical value. The micro controller unit compares the second concentration of the cigarette smoke sensed by the second sensor and a preset a second-1 critical value. When the first concentration and the second concentration are respectively reached to the first-1 and second-1 critical values, the micro controller unit determines as a first alerting mode. When the first concentration and the second concentration are not respectively reached to the first-1 and second-1 critical values, the micro controller unit determines as a monitoring mode.;COPYRIGHT KIPO 2012
