1. A movable object for detecting an obstacle, 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:
calculate a distance from the movable object to the obstacle based on data from at least one of the first passive infrared sensor or the one or more second passive infrared sensors; and
determine whether to effect a collision avoidance maneuver for the movable object to avoid the obstacle based on the distance.
