[0047] like Figure 1 As shown, the humidity detection unit 210 and the temperature detection unit 220 are digital temperature and humidity detection chips U10, which are small in size, low in cost, and resistant to interference. The VDD terminal of the digital temperature and humidity detection chip U10 is connected to the VBUS pin of the TYPE-C female connector 100, and the GND terminal is connected to the GND pin of the TYPE-C female connector 100. The detection input terminal of the digital temperature and humidity detection chip U10 is connected to the humidity detection chip 112, and the DA terminal is the humidity detection output terminal 113, which is connected to the control unit. The digital temperature and humidity detection chip U10 is a custom chip.

[0048] like Figures 2 to 4 As shown, the humidity detection unit 210 is any one of the following: operational amplifier circuit, transistor amplifier circuit, and field-effect transistor amplifier circuit.

[0049] The operational amplifier circuit includes: operational amplifier U11, the non-inverting input terminal of operational amplifier U11 is connected to humidity detection chip 112 and fifth resistor R5, the other end of fifth resistor R5 is connected to VBUS pin of TYPE-C female connector 100, the inverting input terminal of operational amplifier U11 is connected to sixth resistor R26 and seventh resistor R27, the other end of sixth resistor R26 is connected to GND pin of TYPE-C female connector 100, the other end of seventh resistor R27 is connected to VBUS pin of TYPE-C female connector 100, and the output terminal of operational amplifier U11 is humidity detection output terminal 113;

[0051] Furthermore, the difference between a transistor amplifier circuit and a field-effect transistor amplifier circuit lies in replacing the third field-effect transistor Q1 in the field-effect transistor amplifier circuit with a transistor.

[0052] like Figure 5 and Figure 6 As shown, the female connector 100 is a TYPE-C female connector 100, and the male connector is a TYPE-C male connector. The TYPE-C male connector is inserted into the cavity of the TYPE-C female connector 100.

[0053] The tongue 111 of the TYPE-C female connector 100 is located inside the cavity of the TYPE-C male connector. A humidity detection plate 112 of the humidity detection unit 210 is provided on the tongue 111 of the TYPE-C female connector 100 or on the side wall of the cavity of the TYPE-C female connector 100.

[0055] like Figure 5 and Figure 6 As shown, the humidity detection chip 112 is close to the VBUS PIN or GND PIN of the TYPE-C female connector 100. When there are water droplets or water vapor on the humidity detection chip 112, it can be better sensed by the VBUS PIN or GND PIN of the TYPE-C female connector 100 to conduct voltage, and perform leakage current / humidity detection and identification.

[0056] The GND pin of the TYPE-C female connector 100 is longer than the VBUS pin, so that when the TYPE-C male connector is inserted, the GND pin is first connected to the GND pin of the TYPE-C female connector 100 to avoid surge.

[0057] like Figure 5 and Figure 6 As shown, the CC1 or CC2 pin of the TYPE-C female connector 100 is connected to a pull-down resistor for charging voltage identification.

[0058] like Figure 5 and Figure 6 As shown, a humidity detection piece 112 is provided on the top or bottom surface of the tongue 111 of the TYPE-C female connector 100. The humidity detection piece 112 is shorter than the VBUS pin of the TYPE-C female connector 100 to avoid contact with the pin of the TYPE-C male connector. Furthermore, the humidity detection piece 112 is shorter than the other pins on the tongue 111 of the TYPE-C female connector 100.

[0059] like Figure 5 and Figure 6 As shown, the humidity detection plate 112 is installed in a recessed position below the top or bottom surface of the tongue 111 of the TYPE-C female connector 100, or below the side wall of the cavity of the TYPE-C female connector 100; wherein, the humidity detection plate 112 can also be flush with the top or bottom surface of the tongue 111 of the TYPE-C female connector 100; to avoid contact with the TYPE-C male connector and thus affect the humidity detection.
