DESCRIPTION

· The ezPyroTM SMD+ infrared detector extends the ezPyro family for sensing wavelengths above 5 µm.

· It is designed for NDIR detection of anesthetic, refrigerant, and exhaust gases.

· Combines high-quality sensors with configurable electronic integration in a small SMD package.

· Features high sensitivity and fast response times for rapid and accurate gas detection.

· Integrates a digital, current mode read-out for lower IR-emitter duty cycles and reduced power consumption.

· Offers programmable gain and filtering for flexible system design.

· Utilizes industry-standard I2C communication for easy connectivity and calibration.

· Ensures long-term stability and maintenance-free operation.

· Supports daisy-chaining for synchronized sampling across devices.
