The passive infrared (PIR) sensor market is experiencing significant growth as demand for efficient motion detection and ...

The interesting part of these cameras are the PIRs, the passive infrared sensors. They work by monitoring the temperature in front of the device: When a change is detected, the sensor can trigger ...

Dr. Altepeter and DARPA hope to begin to do that by investigating the basic science necessary to give unmanned vehicles entirely passive infrared sensors to navigate.
