BROADCOM AFBR-S6EPY12231R Pyroelectric Infrared Gas Sensor, CO2, 1 Channel, 1.65mm, SMD 5.65mm x 3.7mm x 1.55mm

AFBR-S6EPY12231R is an ezPyro thin film digital (SMD) I²C pyroelectric IR sensor with 4.26µm / 180nm filter for CO2 detection. The high sensitivity combined with fast response times ensures rapid and accurate detection of target gases. These sensors integrate a digital, current-mode read-out that enables lower IR-emitter duty cycles, thereby saving significantly on system-level power consumption, while maintaining high SNR. The industry standard I²C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. The ezPyro sensor is very stable over time, ensuring a long and maintenance-free operational lifespan. Applications include gas sensing: CO2, CO, CH4, NO, anesthetics, refrigerants, exhaust gases, etc, flame detection: CO2 and H2O gases from hydrocarbon or hydrogen flames, food and oil analysis: sugars, proteins, fats, base and acidic numbers, motion detection, gesture recognition.
