In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A can be of a wide variety, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message. And when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

The gyro sensor 180B may be used to determine the motion attitude of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., X, Y and the Z axis) may be determined by gyroscope sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 through a reverse movement, thereby achieving anti-shake. The gyroscope sensor 180B may also be used for navigation, somatosensory gaming scenes.

The acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically three axes).

The ambient light sensor 180L is used to sense the ambient light level. Electronic device 100 may adaptively adjust the brightness of display screen 194 based on the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust the white balance when taking a picture. The ambient light sensor 180L may also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

The fingerprint sensor 180H is used to collect a fingerprint. The electronic device 100 can utilize the collected fingerprint characteristics to unlock the fingerprint, access the application lock, photograph the fingerprint, answer an incoming call with the fingerprint, and so on.

The temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 implements a temperature processing strategy using the temperature detected by temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device 100 heats the battery 142 when the temperature is below another threshold to avoid the low temperature causing the electronic device 100 to shut down abnormally. In other embodiments, when the temperature is lower than a further threshold, the electronic device 100 performs boosting on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194. In other embodiments, the touch sensor 180K may be disposed on a surface of the electronic device 100, different from the position of the display screen 194.

The bluetooth module of the tag device can be always maintained in a low power consumption standby state. When the tag device is awakened by the electronic device through Bluetooth, the tag device interactively selects a UWB channel which is the same as that of the electronic device through Bluetooth, and then a UWB module of the tag device is opened to carry out UWB communication. In the whole interaction process, the Bluetooth of the tag device is always kept in the starting state, the UWB module can be started only in the ranging process, and other processes in the middle can experience the sleep state.

The first preset time period and the first preset times can be set by the user or defaulted by the system.

Further, if the network parameter confirmation message indicates that the network parameter configuration of the tag device fails, the network parameter corresponding to the idle network is sent to the tag device again through bluetooth communication. If the network parameter confirmation message indicates that the network parameter configuration of the tag device is successful, the horizontal antenna can be opened, ranging information is sent to the tag device through UWB communication, after the sending is completed, the first UWB module can be switched to a receiving state, further, the tag device is received through the first UWB module to return, when the receiving fails (the reply of the tag device is not received), the ranging is carried out again, if the reply of the tag device is not received within the second preset time period and the second preset times, the Bluetooth connection can be carried out again, the UWB network configuration can be carried out on the tag device subsequently, and the ranging can be carried out again. If the first UWB module successfully receives the return of the tag device, the distance between the horizontal antenna and the tag device and the angle in the horizontal direction are calculated based on the return, then the vertical antenna is opened, the distance measurement information tag is sent through UWB, after the sending is completed, the first UWB module is switched to a receiving state, the tag return is received through the first UWB module, if the tag return is successfully received, the distance in the vertical direction and the distance in the distance are calculated based on the return, if the receiving fails (the reply of the tag device is not received), the distance measurement is carried out again, if the return of the tag device is not received within the second preset time period and the second preset times, the Bluetooth connection and the subsequent UWB network configuration and distance measurement can be carried out again on the tag device.
