The invention aims at providing an IoT intelligent cup tray and an intelligent drinking water monitoring method thereof. The IoT intelligent cup tray comprises a cup tray, wherein the cup tray is in adisc-shaped structure; a
light guide plate which is in a disc-shaped structure and is used for placing a cup body is arranged in the cup tray; a fixing hole in the
light guide plate is fixedly connected with a
control circuit board by a fixing screw; the
control circuit board used for intelligently detecting the volume of drinking water and the drinking behavior is arranged between the
light guide plate and the cup tray; a
reed switch magnetic switch is arranged at the bottom of the
control circuit board; an acceleration sensor, a
wireless transmission module and an
LED lamp effector are arranged on the control circuit board; the acceleration sensor, the
wireless transmission module and the
LED lamp effector are connected with the control circuit board to form an intelligent drinking water detection
system used for detecting the volume of the drinking water and the drinking behavior, so that the drinking behavior of a guest can be identified, a special lamp effect can be displayed byan LED, the drinking volume of the gust can be intuitively displayed in front of a service staff or a
shopkeeper, and the drinking water can be added timely. Therefore, the service is more timely andmore considerate, and the guest can obtain more considerate and more intimate service.
