20180911· PIR Sensor Functions. First, realize that everything — humans, animals, even inanimate objects — emit a certain amount of IR radiation. How much IR radiation they emit relates to the body or object’s warmth and material makeup. Humans can’t see IR, but we’ve designed electronic detection devices to pick up these signals. PIR sensors are used in thermal sensing applications, such as ...

20190803· Difference between PIR Sensor and Motion Sensor. The motion sensor: Able to detect the movement of people or objects. In most applications, these sensors are mainly used to detect human activities in a specific area. Converts motion into electrical signals: the sensor either emits stimuli and monitors any changes reflected back, or acquires signals from the moving object itself. Alarm: Sounds ...

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

+

20140128· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

20140128· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can ''see'' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When ...
