BROADCOM AFBR-S6PY2572 Pyroelectric Infrared Gas Sensor, CO2 (Medical), 2 Channel, 2.6 x 2.6mm, TO-39

AFBR-S6PY2572 is a thin film analogue pyroelectric dual-channel IR sensor with a 4.90µm / 130nm filter and a 4.26µm / 180nm filter for gas detection and other substance concentration measurements offer exceptionally high responsivity, low microphonics and class leading thermal and electrical stability. The main use of this device is CO2 detection for medical applications. This high-performance current mode sensor achieves a signal-to-noise of ~10,000 and offers a fast, stable response over a wide operating frequency range. The sensor elements are built into a low noise circuit that has an internal CMOS op amp, with a 10Gohm feedback resistor outputting a voltage signal centred on half the supply rail. Applications include NDIR gas detection, flame detection, NDIR pellistor and electrochemical replacements, automotive gas analysis, medical gas analysis, anaesthesia, fluid analysis, food safety, THz detection, energy measurement, miniaturized designs.
