QGS Pyroelectric Infrared Gas Sensors

KEMET's QGS thin film digital pyroelectric IR sensors for gas detection and concentration measurement combine high sensitivity with fast response times and high dynamic range to ensure rapid and accurate detection of target gases. These high-quality sensors in a small SMD package integrate a digital, current mode readout that enables lower IR emitter duty cycles, saving significantly on system-level power consumption, while maintaining high SNR. Industry-standard I²C communication enables plug-and-play connectivity to microcontrollers and allows easy tuning and calibration. Programmable gain and filtering offer maximum flexibility in system design and various optical filter options are also available. These sensors can be connected in linear series to allow synchronized sampling across devices. The long and maintenance-free operational lifetime makes them ideal for highly demanding automotive or medical applications.
