Abstract: An oven has a sensor including a light-emitting portion for outputting light in a first wavelength band and light in a second wavelength band and a light-receiving portion for receiving light reflected from a cooking product in the oven. A processor to, when a user command for initiating cooking is input, output the light in the first wavelength band through the light-emitting portion. When the light output from the light-emitting portion is reflected from the cooking product and received by the light-receiving portion, the processor determines the size of the cooking product on the basis of the received light in the first wavelength band, and outputs the light in the second wavelength band through the light-emitting portion while the cooking product is being cooked on the basis of a cooking time determined according to the determined size of the cooking product.

Abstract: A dryer is disclosed. The dryer includes a heat exchanger configured to remove moisture from air flowing and heat and discharge the moisture-removed air, a drum containing a material to be dried, a humidity sensor configured to detect a humidity of the air flowing from the drum, a fan configured to generate a flow of the air flowing along a flow path formed so that the air discharged from the heat exchanger flows to the heat exchanger via the drum and the humidity sensor, and a processor configured to determine a dried state of the material to be dried based on the humidity detected through the humidity sensor, and the humidity sensor is disposed at a position where a flow velocity of the air is equal to or higher than a predetermined velocity in the flow path formed between the drum and the heat exchanger.

Abstract: A moving apparatus for cleaning includes: a cleaner configured to perform cleaning; a traveler configured to move the moving apparatus; a sensor including a transmitter configured to transmit a radio frequency (RF) signal toward a front floor, and a receiver configured to receive a reflection signal of the RF signal; and a processor configured to control the traveler to make the moving apparatus travel corresponding to a result of determining that an obstacle is present in the front floor based on a signal pattern detected from the received reflection signal. Thus, the cleaning robot is provided with a radar sensing function using the RF signal, and thus improved in accuracy of detecting an obstacle without being affected by surrounding color, light disturbance and the like environment.
