[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] Please refer to Figure 1-Figure 2 The utility model proposes a sensor, which needs to be used in conjunction with a controller in the car. The controller is installed in the car, and multiple sensors 2 are respectively installed in the grooves of each door handle in the car. The multiple sensors 2 can be wirelessly connected to the controller, and can also be wirelessly connected to Bluetooth speakers or other smart players in other cars. The controller has a speaker, and the sensor 2 includes a shell component 21 and a circuit board 22. The circuit board 22 is fixedly connected to the shell component 21. A battery 23, a distance sensor 24 and a wireless connection module 221 are provided on the circuit board 22. The battery 23 supplies power to the distance sensor module 24 and the wireless connection module The distance sensor module 24 is electrically connected to the wireless connection module 221. The distance sensor 24 can be any one of an ultrasonic distance detection module, an infrared distance detection module, and a capacitive distance detection module, and is used to detect the distance between the passenger's hand and the door handle. The distance sensor 24 detects once every 1 second, or other time intervals, such as 0.5 seconds or 2 seconds. The circuit board 22 can be burned with a detection program when it leaves the factory according to requirements. The distance sensor 24 is fixedly connected to the housing component 21 and protrudes from the upper surface of the housing component 21. The battery 23 and the distance sensor 24 are both connected to the circuit board 22. Electrical connection, the wireless connection module 221 is used to transmit wireless signals to the outside. The wireless connection module 221 can be any one of a Bluetooth module, a WiFi module, and a Lora (long-distance radio) module. The wireless connection module 221 can be wirelessly connected to the controller, and the wireless connection module 221 can also be wirelessly connected to the Bluetooth speaker or other smart player in the car. After the corresponding distance sensor module 24 detects that the passenger's hand is approaching, the wireless connection module 221 returns a signal to the controller, so that the speaker plays a prompt sound. The distance sensor module 24 and the wireless connection module 221 can be an integrated structure or a split structure; if a Bluetooth speaker or other smart player is connected, when the Bluetooth speaker or other smart player has power, the Bluetooth speaker or other smart player and the wireless connection module 221 will handshake and communicate once in 1 minute. If the wireless connection module 221 loses contact with the sound player for 3 consecutive times, it means that the car has stopped and the power has been cut off. The distance sensor 24 will change to detect once every 5 seconds, or stop detecting, which can reduce the power consumption of the battery 23. At this time, the wireless connection module 221 still retains the frequency of receiving once per minute so that the car can enter a normal working state after restarting.

[0025] In this embodiment, the controller is electrically connected to the speaker at the door, and the sensor 2 is installed in each door handle groove in the car. After the corresponding distance sensor 24 detects the passenger's hand approaching, the wireless connection module 221 sends a signal to the outside, and after the controller obtains the signal, the corresponding speaker plays a prompt sound. This signal can also be received by a Bluetooth speaker or other smart player, so that the speaker of the device receiving the signal plays a prompt sound. In this way, there is no need to use the battery 23 to supply the speaker, which effectively reduces the power consumption of the battery 23;
