S201, detecting are near the distance of object.
Concrete, close near what refer in relative distance, it is possible to be active close, it is also possible to be the close of passive type.
Optionally, when user is near an object, or an object is when user, detecting real-time this near the distance of object.
S202, judge detecting distance whether less than default distance threshold.
Concrete, the distance threshold preset defines monitoring early warning range, and user formerly can be configured according to actual demand.
Optionally, for instance user need under particular context to arround be monitored early warning within the scope of 5 meters, distance threshold correspondingly can be set to 5 meters by that.
If S203 judges that the distance of described detecting is less than default distance threshold, then detect this temperature near object.
