Design and implementation of a compressive infrared sampling for motion acquisition
Although there has been a lot of work exploiting the combination of PIR sensors and Fresnel lens arrays to form the multiplexed infrared sensing, establishing the compressed infrared sampling model for acquiring the motion information is an unsolved problem.

Detecting Direction of Movement Using Pyroelectric Infrared Sensors
We have developed a data collection apparatus consisting of four dual sensing-element PIR sensors with Fresnel lenses to modify their field of views and op-amp circuits, and mounted it on the ceiling of a test room.

Design and implementation of a distributed fall detection system based on wireless sensor networks
The PIR sensors with Fresnel lens array are essentially sensi- tive to thermal change, especially at the boundaries of the sampling cells, which are preferable in terms of sen- sing efficiency in the sense of reducing the number of sensors involved without …
