How Do Motion Sensors Work? Types of Motion Sensors ...

· The PIR has two slots made of a special material that is sensitive to infrared. When the sensor senses a differential change between the two slots, this causes a pulse, which is what it detects as “movement”. Figure 1 from Adafruit shows a great example of how it works. Figure 1: PIR sensing heat source movement and outputting pulses ...
