Description

Smart plug combined with carbon monoxide sensor {SMART PLUG COMBINED WITH CARBON MONOXIDE SENSOR}

The present invention relates to a smart plug for combined use of a carbon monoxide sensor, and more particularly, to a smart plug that selectively supplies or cuts off power injected through a plurality of outlets by determining a risk level according to a carbon monoxide concentration.

When various gases are generated and accumulated in the enclosed space, ventilation must be promptly ventilated for health and hygiene and safety maintenance, or the combustion reaction must be stopped by blocking the source at the same time as ventilation.

However, in the past, data linkage between a sensor that detects a gas and a device that blocks the source and a ventilation device is essential, but in most cases, the sensor and the device are not linked, so there is a limitation that technical gas blocking is difficult. Accordingly, a person must detect the gas and cut off the power source of the generator. However, if the person loses consciousness due to the accumulation of gas, there is a problem that a fatal risk is applied to life.
