AFBR-S6EPR44212

AFBR-S6EPR44212 is an ezPyro™ TO I²C pyroelectric infrared flame sensor. This thin film digital pyroelectric sensor for flame detection combines a high-quality sensor with a high level of configurable electronic integration in an industry-standard TO-39 package. High sensitivity combined with fast response times ensures rapid and accurate flame detection. The high dynamic range allows detection of small and large flames, nearby or over larger distances. This sensor integrates a digital, current-mode read-out offering high responsivity over the full frequency range of flame flicker (3-30Hz). Programmable gain and filtering offer maximum flexibility in system design. Industry standard I2C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. This sensor can also be daisy-chained to allow synchronized sampling across devices and offer various low-power modes.
