Sensing device for detecting side ambient light and mobile terminal

The utility model discloses an induction device for detecting side ambient light and a mobile terminal, the induction device is used for being arranged between two adjacent antennas, the two adjacent antennas are arranged on the inner side of a side frame, the induction device comprises an insulation light guide part, the insulation light guide part is arranged between the two adjacent antennas, and the insulation light guide part is arranged on the inner side of the side frame. The ambient light sensor is located on the side, away from the side frame, of the insulating light guide part. The problems that in the prior art, an ambient light sensor has a certain field angle, part of irradiation light does not irradiate in the field angles of the ambient light sensor on the front face and the back face, so that a detection value does not conform to actual ambient light illuminance information, the action of adjusting the screen brightness is mistakenly made, and the user experience is reduced are solved. 本实用新型公开
