Smart digital alarm clock: We can read the exact time on the alarm clock and set two different alarm reminders on it. We offer a personality setting for the alarm reminder. You can set the doorbell to ring every day, on weekdays, and Monday through Saturday. The alarm tone and volume are adjustable. Night light in the bedroom: The digital alarm clock is also a time-controlled night light that can accompany you to sleep and then switch the light off when the timer ends. The maximum time that can be set is 60 minutes, so that no energy is wasted. Kids Sleep Training: The digital alarm clock can mimic sunrise and set lights, which can help us develop good sleep habits. If we set a workout time to 7:00 AM, it will gradually get lighter from 7:00 AM to 7:45 AM. When the training time is at night, the light changes from bright to dark. Sound sensor screen: When the digital alarm clock is not connected to the power supply, the screen goes to sleep. It wakes up for 40 seconds when the environment is louder than 56dB. We can wake it up by clapping, tapping, and speaking. HOMEWORK TIMER & GAME TIMER: We can set a countdown time to schedule the kids' homework, play time and cooking time. It rings for 3 minutes to remind us that the end time has expired. The maximum time that can be set is 59 minutes.
