A device for controlling an electric cooking apparatus, may include one or more processors, memory, and one or more sensors including a carbon monoxide sensor. The one or more processors may determine, based on at least one of an electric signal output from the cooking apparatus or an electric signal output from the one or more sensors, whether the cooking apparatus performs an operation. In response to determining that the cooking apparatus performs an operation, the one or more processors may cause the carbon monoxide sensor to measure a level of carbon monoxide. The one or more processors may determine whether the level of carbon monoxide exceeds a first threshold. In response to determining that the level of carbon monoxide exceeds the first threshold, the one or more processors may control the cooking apparatus to stop performing the operation.
