SENS-51 HC-SR505 Mini Infrared PIR Motion Sensor
These Mini Passive Infrared Sensors work exactly like their bigger brothers, however they take about a fifth to half the size compared to its counterpart! PIR sensors are pyroelectric, meaning that when a motion is detected from the change in the infrared levels it will report active high signal to indicate presence of movement. When there is no movement it will be active low offering a 0v signal to indicate there is no movement near it. Once the unit is triggered you must wait 8 seconds for it to reset.
