[0042] Please refer to Figures 2 to 10 The following is a detailed description of the specific structure of the driver board 13 and the wireless transmission circuit board 14:

[0043] Please refer to Figure 2 , Figure 3 and Figure 4 The gravity decoding chip RP1 is model HX711, and includes a gravity decoding input pin 131 and a gravity decoding output pin 132.

Because the first voltage divider resistor R16 and the second voltage divider resistor R17 can divide the battery voltage signal, the signal input to the data transmission chip U2 is a low-voltage battery voltage signal. This avoids damage to the data transmission chip U2 by a high-voltage battery voltage signal, which helps to extend the service life of the data transmission chip U2. The driver board 13 includes a filter capacitor C11. One end of the filter capacitor C11 is connected to the power supply battery 12 and the first voltage divider resistor R16. The other end of the filter capacitor C11 is grounded. The filter capacitor C11 is used to filter the battery voltage signal. The filter capacitor C11 can filter out interference in the battery voltage signal, making the battery voltage signal more stable and accurate, which helps to improve the reliability of the battery voltage signal.

[0049] The working principle of this utility model is as follows: First, the user turns on the smart coaster 10 and places a water cup on it. The power supply battery 12 supplies power to the smart coaster 10 and outputs a battery voltage signal. Next, the LED D3 of the display module 15 lights up, indicating that the smart coaster 10 is powered on. Furthermore, the gravity sensor 11 of the smart coaster 10 generates a gravity analog signal based on the weight of the water cup. Subsequently, the gravity decoding chip RP1 performs analog-to-digital conversion on the gravity analog signal, generating a gravity digital signal. The first voltage divider resistor R16 and the second voltage divider resistor R17 divide the battery voltage signal. Then, the data transmission chip U2 transmits the gravity digital signal and the battery voltage signal. Subsequently, the wireless transmitter chip U3 receives the gravity digital signal and the battery voltage signal, and wirelessly transmits the gravity digital signal and battery voltage signal to the device terminal 18. The device terminal 18 displays the water level in the cup based on the gravity digital signal and displays the power level of the power supply battery 12 based on the battery voltage signal. When the power supply battery 12 is low on power, since the charging chip U5 is connected to the first external power source, the user can charge the power supply battery 12 with a constant current through the charging chip U5.
