Advantages of PIR sensor | disadvantages of PIR sensor

Following are the drawbacks or disadvantages of PIR sensor: They have lower sensitivity and less coverage compare to microwave sensors. It does not operate greater than 35 degree C. It works effectively in LOS (Line of Sight) and will have problems in the corner regions. It is insensitive to very slow motion of the objects. Since PIR sensors sense heat signatures in room, they are not very sensitive if …
