METHOD AND APPARATUS FOR AUTO EXHAUST USING SMART DEVICE WITH GAS SENSOR

摘要

The present invention provides an automatic exhaust device and a method using a smart device with a gas sensor capable of automatically exhausting when harmful gas to human bodies is detected by connecting a portable, small, and high efficient gas sensor module to a smart device to analyze gas information sensed by the gas sensor module with the smart device. The automatic exhaust device using a smart device with a gas sensor comprises: an exhaust system (300) to exhaust harmful gas from a working space; a low-power gas sensor module (100) to sense the harmful gas; a smart device (200) electrically connected to the low-power gas sensor module (100) to supply power, to analyze gas information sensed by the low-power gas sensor module (100), and to generate an exhaust system driving signal when the gas information is a harmful level to human bodies; and an exhaust system control device (400) to control a driving of the exhaust system in accordance to the exhaust system driving signal received from the smart device (200).
