The invention discloses a method and
system for utilizing distance sensing to reduce
mobile phone radiation. The method includes the steps of S1, answering a
mobile phone; S2, utilizing a distance sensor to detect the distance between a tested target and the
mobile phone; S3, judging whether or not the distance between the target and the mobile phone satisfies a preset condition and obtaining a judgement result; S4, according to the judgement result, conducting corresponding adjustment on the
radio frequency power of the mobile phone. The
system includes a
signal detection module, a comparisonmodule connected with the
signal detection module and an adjustment module connected with the comparison module; the
signal detection module detects the distance between the mobile phone and the
cheek of a user; the comparison module compares the distance detected between the mobile phone and the
cheek of the user by the signal detection module with a
set distance to determine whether or not thedistance between the mobile phone and the
cheek of the user is in accordance with the
set distance, and obtains a judgement result; the adjustment module carries out corresponding adjustment on the
radio frequency power of the mobile phone according to the judgement result. The method and
system can be used for reducing the
radio frequency power when it is detected that the cheek of the user approaches the mobile phone, the mobile phone
radiation is decreased without adding SAR sensors and increasing the cost of hardware, and the practicability is high.
