For example, if the user selects the soup-making mode, a reminder will be issued every ten minutes for one hour, and each reminder will last three minutes. If no one is detected in the kitchen within three minutes after the reminder starts, the alarm mechanism will be triggered immediately. When the user receives the reminder and goes to the kitchen, the device will automatically cancel the alarm when it detects a human body. There are various alarm methods, including high-decibel buzzer on-site alarm, mobile phone APP remote push alarm information and optional SMS / phone notification, to ensure that users can be informed of the situation in a timely manner no matter where they are.
