1. A movable object for responding to an object, comprising:
a first passive infrared sensor having a first detection range and a first field of view;
one or more second passive infrared sensors each having a second detection range and a second field of view, the second detection range being longer than the first detection range and the second field of view being smaller than the first field of view; and
one or more processors configured to:
recognize the object based on one or more heat signals received from at least one of the first passive infrared sensor or the one or more second passive infrared sensors; and
perform a flight response measure to control the movable object based on the recognized object.
