Description
Passive infra red (PIR ) sensors activate when an object crosses one of the infrared beams that the sensor emits, while Microwave sensors use the same principles as radar. They send out a pulse of energy and measure the returning value. Sensors can cover a wide variety of angles and areas depending on your needs and, if you have pets, there are sensors that can distinguish between animals and humans so that your pets don't set your alarm off.
