Smart digital alarm clock: We can read the exact time on the alarm clock and set two different alarm reminders. We offer a personality setting for snooze. You can set the doorbell every day, weekdays and Monday to Saturday. 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 turn off the light when the timer ends. The maximum time that can be set is 60 minutes, so no energy is wasted. Children's sleep training: The digital alarm clock can imitate the sunrise and adjust the lights, which can help us develop good sleeping habits. If we set a training time at 7:00 a.m., it will gradually become lighter from 7:00 a.m. to 7:45 a.m. When the drive time is at night, the light changes from bright to dark. Sound Sensor Screen: When the digital alarm clock is not connected to power, the screen will go to sleep. It wakes up for 40 seconds when the environment is louder than 56dB. We can wake it up by clapping, tapping and talking. HOMEWORK TIMER & GAME TIMER: We can set a countdown timer to schedule children's homework, play time and cooking time. It rings for 3 minutes to remind us that the end time has expired. The maximum duration that can be set is 59 minutes.
