Broadcom AFBR-S6EPY eZPyro™ Pyroelectric IR Sensors

Broadcom® AFBR-S6EPY eZPyro™ Pyroelectric Infrared (IR) Sensors are thin film digital pyroelectric sensors that combine high-quality sensors with a high level of configurable electronic integration. These pyroelectric SMD sensors feature high sensitivity combined with fast response times to ensure rapid and accurate detection of gases/flames. The pyroelectric IR sensors also feature ultra-low power, sleep modes, wake-up-by signal, fast switch-on, open API, and EMI immunity. These sensors communicate through industry-standard I2C, which enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration.

The AFBR-S6EPY12111B and AFBR-S6EPY12121B sensors come on a breakout PCB. The AFBR-S6EPY12111B sensor is the rigid or flexible connection for easy prototyping which is equipped with a 5μm long pass filter. The AFBR-S6EPY12121B is an out-of-the-box sensor readout tool that is equipped with a 2.2μm long pass filter with a 2.5μm to 6μm filter bandwidth range. Typical applications include gas sensing, flame detection, motion detection, and gesture recognition.
