Our company has developed a device with a timer and a connection to a server to determine the time zone and the time of sunset and sunrise in a specific location where this device is installed.
The device is connected to LED lighting, which, when the windows are closed, can simulate the glow at sunrise and sunset, notifying the owner of the time of day.
Also in the functionality of this device, there is the ability to set a timer to turn on the “alarm clock”, which will reproduce the sunrise, waking a person from sleep.
