Product Overview
The Broadcom ezPyro SMD I2C Pyroelectric IR sensors are designed for high-performance flame detection. These thin-film digital sensors integrate advanced electronics within a compact SMD package, offering high sensitivity and rapid response times for accurate flame identification. Their high dynamic range enables the detection of flames of varying sizes and distances. Featuring a digital, current-mode readout, these sensors provide high responsivity across the typical flame flicker frequency range (3 to 30 Hz). Programmable gain, filtering, and sampling rates, along with configurable low-power modes, offer significant flexibility in system design. The industry-standard I2C communication ensures plug-and-play connectivity to microcontrollers for easy tuning and calibration. These sensors are characterized by their long-term stability, ensuring a maintenance-free operational lifespan. Options for daisy-chaining allow for synchronized sampling across multiple devices.
