Abstract: An image acquiring method includes: detecting whether a screenshot signal is triggered; sending a screenshot request to a server when the screenshot signal is triggered, the screenshot request including a user account and a target smart device identification, so as to enable the server to send the screenshot request to a target smart device based on the user account and the target smart device identification; and receiving a screenshot image from the server, the screenshot image being obtained by using the target smart device to perform a screenshot on an image displayed on the target smart device based on the screenshot request.

Abstract: Aspects of the disclosure provide a method for detecting an arrival of a user in a target area. The method includes searching, by a device belonging to the user, for a target wireless access device located in the target area at a preset frequency according to an instruction, when the target wireless access device is found, establishing a connection with the target wireless access device; and after the connection with the target wireless access device is established, determining that the user arrives at the target area.

Abstract: A plant monitor includes: a main control chip, a wireless communication chip connected with the main control chip, and at least one growth environment monitoring sensor connected with the main control chip. The at least one growth environment monitoring sensor includes at least one of an illumination sensor, a temperature sensor, a humidity sensor, or a soil conductivity sensor. The main control chip is configured to acquire growth environment data collected by the at least one growth environment monitoring sensor, and send the growth environment data to a mobile terminal via the wireless communication chip. The mobile terminal is configured to generate plant cultivation reference information according to the growth environment data.

Abstract: The disclosure relates to a method and apparatus for accessing a wireless network. The method includes receiving, by a first device, a first broadcast message from a second device intending to access the wireless network; generating notification information based on the first broadcast message, wherein the notification information is configured to notify a user via the first device that the second device is requesting access to the wireless network; receiving an input from the user based on the notification information; and sending a request message to a wireless router in response to the input, wherein the request message is configured to instruct the wireless router to broadcast a second broadcast message including access information for accessing the wireless network via the wireless router.

Abstract: Methods, devices, and computer-readable media for adjusting volume are provided in the disclosure. A method for adjusting volume may include acquiring, with a device, ambient noise information about ambient noise present during playing of sound. The method may further include adjusting volume of the sound based on the acquired ambient noise information. By acquiring ambient noise information, the method may provide that volume of the sound is adjusted based on the acquired ambient noise information. Because the acquired ambient noise information may reflect the current ambient noise level, the method may adjust volume of the sound based on the acquired ambient noise information without requiring manual adjusting of volume by a user, which may be convenient to the user.
