Household appliance control circuit and system

The utility model relates to a household electrical appliance control circuit and system, the household electrical appliance control circuit comprises a sensor, a first controller and an infrared control circuit, the sensor can collect a heart rate signal of a user wearing an earplug device, and when the heart rate signal represents that the user is in a sleep state, the infrared control circuit sends the infrared control circuit to the first controller. The first controller sends out a first control signal to the infrared control circuit, so that the infrared control circuit sends out an infrared signal to control the household appliance to be turned off. Therefore, when the user is in the sleep state, the infrared control circuit automatically emits infrared light and controls the household appliance to be automatically turned off, energy is saved, and meanwhile, compared with the mode that the household appliance is controlled to be turned off through a remote controller, the infrared control circuit is mo
