Abstract: An air conditioning device includes an air purifier, a sensor, a communicator, and a processor. The sensor is configured to measure an air pollution level. The communicator comprises circuitry and configured to communicate with a server. The processor is configured to activate the sensor in a state where the air purifier is not driven, in response to receiving a first signal requesting an air pollution level state information from the server based on a location of a mobile terminal, transmit a second signal indicating that the air conditioning device needs to be driven to the server based on the air pollution level measured by the sensor, and drive the air purifier in response to a driving instruction received from the server.

Abstract: An electronic apparatus and a controlling method thereof are provided. A server apparatus communicatively connected with a plurality of electronic apparatuses constituting an internet of things (IoT) includes a communication interface, and a processor configured to, based on receiving a request of a service from an application executed in a user terminal apparatus being received through the communication interface, determine data corresponding to the request and an electronic apparatus for receiving the data among the plurality of electronic apparatuses, determine a time cycle for receiving the data from the electronic apparatus based on the service, control the communication interface to transmit a request for transmitting the data according to the time cycle to the electronic apparatus, and based on receiving the data from the electronic apparatus at an interval of the time cycle through the communication interface, provide the service based on the received data.
