Ding / Doorbell


The water falls into the water to create a ripple, and the design of the "vibrating bracelet doorbell" takes shape. It can help the hearing impaired to know in time that there are guests to visit, and the way of silent vibration can help to avoid disturbing others' rest in the night. When the guest touches the doorbell, the vibrating bracelet begins to vibrate to alert the owner. The quiet and gentle reminder mode is effective and direct. The technological innovation of the Internet of Things reflects humanistic care.
