· PIR sensor is a low-cost motion detector sensor. It is a passive motion sensor that means it can only detect something around it and it cannot transmit anything. Whenever there is a motion around the sensor, it will detect the heat of the human body and produces a high output logic 1 at the output of the sensor. Every object emits infrared rays when they are heated and on the same principle, the human body emits IR rays due to body heat. Hence, whenever the motion sensor …
