Because the spatial position of the intelligent water cup is constantly changed, such as pouring, carrying and washing, in order to accurately obtain the water drinking amount of the user, whether the user drinks water needs to be judged in a combined manner, and therefore the detection parameters of the water level detection sensor are corrected. The gravity Sensor (G-Sensor) is also called an acceleration Sensor, and senses a change in acceleration, and is expressed using an acceleration component in a three-dimensional direction. The G-Sensor is used in a plurality of intelligent devices, for example, the G-Sensor is built in a high-end notebook computer of IBM, and when the G-Sensor is violently pulled (such as dropped), the hard disk protection is immediately started to avoid the damage of the hard disk. And the direction of a mobile phone screen is sensed by using a G-Sensor like an iPhone of Apple, when the mobile phone is horizontally placed when a video is watched, the screen automatically rotates along with the mobile phone screen, and the user experience is greatly increased.
The gravity sensor can also adopt an attitude sensor, and the attitude sensor is a high-performance three-dimensional motion attitude measurement system based on the MEMS technology. The system comprises motion sensors such as a three-axis gyroscope, a three-axis accelerometer and a three-axis electronic compass, and data such as a three-dimensional attitude, an azimuth and the like subjected to temperature compensation are obtained through an embedded low-power ARM processor. And outputting zero-drift three-dimensional attitude and azimuth data expressed by quaternion and Euler angle in real time by using a quaternion-based three-dimensional algorithm and a special data fusion technology. The LPMS series and the iAHRS-M0 attitude sensors can be widely embedded into model airplane unmanned aerial vehicles, robots, mechanical holders, vehicles and ships, ground and underwater equipment, virtual reality, human motion analysis and other product equipment which need to independently measure three-dimensional attitude and orientation.

During the use, liquid makes the response electromotive force between the response metal diaphragm change when drinking water mouth 41, is also that the electric charge amount between two detection electrodes changes, forms the detected signal, and same reason, when the user drinks water, the mouth contacts electrically conductive silica gel layer 51 for the electric charge amount on the upper induction metal diaphragm changes, thereby produces the detected signal.
When the inductive capacitor works, a potential difference is formed between the inductive metal diaphragms, which is equivalent to a capacitor, and the induced electromotive force is detected in a current mode according to the principle of capacitance charge and discharge. As shown in the figure, the detection electrode is grounded through a virtual short circuit of an operational amplifier, and the electric charge quantity on the detection electrode can be changed due to the alternating change of the induced electromotive force generated in the fluid along with the excitation magnetic field, so that a current operational amplifier is formed, and then a current signal is converted into a voltage signal through a negative feedback circuit.
According to the characteristics of the capacitor, the charge quantity stored on the polar plate of the detection electrode is Q ═ CiE
Wherein G is the capacitance of the electrode, and E is the induced potential. Q is further expressed as
Therefore, a flow signal can be obtained by detecting the current. Due to the adoption of the virtual ground technology, the method has no requirement on the input impedance of a circuit, and can detect the fluid with low conductivity. However, as can be seen from the expression, the flow signal detection and the electrostatic capacitance CfThe capacitance formed between the detection electrode and the medium changes due to the influence of temperature and pressure, and measurement errors are caused. The capacitance must be compensated for temperature, pressure, etc. to ensure accuracy. As shown in FIG. 3, the electrode is measured by calculationThe amplifier is "virtual short" grounded, and the induced electromotive force generated in the fluid is changed along with the alternating change of the exciting magnetic field, so that the charge quantity on the detection electrode is changed, and the current is formed. The operational amplifier converts the current signal into a voltage signal through the negative feedback circuit.
