DESCRIPTION

· KEMET's QGS thin film digital pyroelectric IR sensors are designed for gas detection and concentration measurement.

· These sensors offer high sensitivity, fast response times, and a high dynamic range for rapid and accurate gas detection.

· They come in a small SMD package and integrate a digital, current mode read-out for lower IR-emitter duty cycles, reducing system-level power consumption while maintaining high SNR.

· The sensors support I2C communication for easy connectivity to microcontrollers, allowing for simple tuning and calibration.

· They feature programmable gain and filtering for flexible system design and offer various optical filter options.

· The sensors can be connected in linear series for synchronized sampling across devices, making them suitable for demanding automotive or medical applications.
