Abstract: The present invention relates to an apparatus and a method for detecting a water level, which are capable of generating a water level detection signal which is alternating current output to a water level detection sensor by using two direct current control signals alternately output from a micom.

Abstract: Provided is a carbon monoxide (CO) leak alerting device and method, and more specifically, a CO leak alerting device and method, whereby, by operating on the basis of the Internet of Things (IoT), a CO leak caused by damage to a boiler flue is detected, an alert is issued through two or more among the CO leak alerting device, a boiler controller and a wall pad, boiler ventilation and indoor air ventilation are automatically carried out when the leak is determined to have occurred, and authorities relevant to the CO leak, and a user are directly notified of the CO leak.

Abstract: The present disclosure relates to a system and a method for discharging carbon monoxide (CO) by using a CO leakage alarm device and, more specifically, to a system and a method for discharging CO by using a CO leakage alarm device, the system and the method being operated on the basis of the Internet of things (IoT) so as to: detect CO leakage caused by damage to a boiler flue and sound an alarm through at least two from among the CO leakage alarm device, a boiler controller, a wall pad, and the like, automatically perform boiler ventilation and indoor air ventilation when the leakage is determined; and directly notify CO leakage-related authorities and users about the CO leakage.

Abstract: The present disclosure relates to a gas and earthquake detector, a gas and earthquake remote monitoring system using the same and a method thereof, and more particularly, to a gas and earthquake detector, a gas and earthquake remote monitoring system using the same and a method thereof, which detect a plurality of gases and earthquakes, detect and autonomously warn gas leakage of a plurality of detection target devices sensitive to the gas and the earthquake, and the earthquake around the detection target device, and easily register the gas leakage and the earthquake in a remote management means through a user mobile terminal of a user to monitor the gas leakage of the detection target device and the earthquake at a detection target device location through the remote management means.

Abstract: The present invention relates to an apparatus and method for detecting an earthquake using an accelerometer. More particularly, the present invention relates to an apparatus and method for detecting an earthquake using an accelerometer, the apparatus and method being capable of improving reliability of acceleration data obtained from the accelerometer and reliably determining whether an earthquake has occurred on the basis of a change between current acceleration data and previous acceleration data.
