Abstract : Pyroelectric sensors are low-cost, low-power small components commonly used to trigger alarm in the presence of humans or moving objects by means of black body radiation, the use of an array of pyroelectric sensors can lead to extraction of more features such as direction of movements, speed, number of people and other characteristics.
In this work a low-cost pyroelectric infrared sensor based wireless network is set up to be used for tracking people motion. A novel technique is proposed to distinguish the direction of movement and the number of people passing.
The approach has low computational requirements, therefore it is well-suited to limited-resources devices such as wireless nodes.
