Plug-in air quality detector, control method and control device

A method, comprising:

• connecting, a plug-in air quality detector comprising:
• a connector component, a sensor component, and a control circuit disposed inside a casing, with a user device via the connector component, wherein the control circuit is electrically connected with the sensor component and the connector component respectively;
• acquiring, by the control circuit, an air quality parameter of air around the plug-in air quality detector measured by the sensor component;
• and
• giving a prompt by the control circuit according to the air quality parameter.

A control circuit, the control circuit comprising:

• a processor that is electrically connected with a sensor component and a connector component in a plug-in air quality detector;
• and
• a memory configured to store instructions executable by the processor,
• wherein the processor is configured to:
• when the plug-in air quality detector is connected with a user device via a connector component in the plug-in air quality detector, acquire an air quality parameter of air around the plug-in air quality detector measured by the sensor component;
• and
• give a prompt according to the air quality parameter.
