SENS-51 HC-SR505 Mini Infrared PIR Motion Sensor

These Mini Passive Infrared Sensors work exactly like their bigger brothers; however, they take about one-fifth to one-half the size compared to their counterparts! PIR sensors are pyroelectric, meaning that when motion is detected from the change in infrared levels, it will report an active high signal to indicate the presence of movement. When there is no movement, it will be active low, offering a 0v signal to indicate that there is no movement near it. Once the unit is triggered, you must wait 8 seconds for it to reset.
