Description
technical field [0001] The present application belongs to the field of electronic technology, and specifically relates to an electronic device, a control method and a control device. Background technique [0002] At present, wireless communication technology is used in electronic equipment, and wireless communication technology will generate electromagnetic radiation, and the excessive electromagnetic radiation will cause certain harm to human health. [0003] In order to solve this problem, an electromagnetic wave absorption ratio (Specific Absorption Rate, SAR) sensor is added to the electronic device, and the transmitting antenna in the electronic device is used as the detection antenna of the SAR sensor. The corresponding detection method is: when the target object is close to the transmitting antenna, the SAR sensor can detect the capacitance change of the transmitting antenna. When the capacitance changes to exceed a certain threshold, the target object is considered t...
