Broadcom ezPyro thin film digital (SMD+) I²C pyroelectric sensor

Gas sensor, 1 ch, digital, SMD

Ideal for industrial-scale and forest flame detection detecting up to 70 m distance. The ezPyro SMD+ range of thin film digital pyroelectric extended range IR sensors for flame 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 ensures rapid and accurate flame detection. The high dynamic range allows detection of small and large flames, nearby or over larger distances. These sensors integrate a digital, current mode read-out offering high responsivity over the full frequency range of flame flicker (3-30 Hz). This ezPyro SMD+ detector is equipped with a filter with 9.50 µm and a filter BW of 400 µm. 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. ezPyro+ sensors are very stable over time ensuring a long and maintenance-free operational lifespan. Various optical filter options are available. These sensors can also be daisy-chained to allow synchronized sampling across devices and offer various low power modes. This product is lead-free and compliant with RoHS.
