Anmbest 5PCS DC 2.7-12V AM312 IR Pyroelectric Infrared PIR Motion Sensor Detector Module Repeat Trigger for Arduino Microcontrollers

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.
