ePY2211X (SMD) (3.4) PRELIMINARY TM 2 ezPyro I C Pyroelectric Infrared Motion Sensor (SMD) Introduction The ezPyro range of thin film digital pyroelectric IR sensors for motion detection combines high quality sensors with a high level of configurable electronic integration in a small SMD package. High sensitivity combined with fast response times ensure rapid and accurate motion detection. High dynamic range allows motion detection nearby or over larger distances. These sensors integrate a digital, current mode read-out that enables lower IR-emitter duty cycles, thereby saving significantly on system level power consumption, while maintaining high SNR. Programmable gain and filtering offer maximum flexibility in system design. 2 Industry standard I C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning. These sensors can also be daisy-chained to allow synchronized sampling across devices and offer various low power modes, including a wake-up by motion feature. The 2x2 pixel version of this device allows users to determine direction of motion.
