Gas Sensors QGS Pyroelectric Infrared Gas Sensors, I2C-SMD Overview Applications 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. • Gas and gas flues • HVAC (refrigerant or CO2-driven ventilation system) • Industrial process and safety • Medical capnography and anesthesia • Handheld breath analysis and breath rate measurement • Breath actuated dispenser • Automotive cabin air quality • Exhaust (CO2 content) • Home and building technology • Environmental monitoring (ambient CO2 level) • Pollution air quality in home, office and car (excessive CO2 level) These high quality sensors, in their small SMD package, integrate a digital, current mode read-out that enables lower IR-emitter duty cycles, thereby savingsignificantly on system level power consumption, while maintaining high SNR. Industry standard I2C communication enables plugand-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 together in linear series to allow synchronized sampling across devices. Their long and maintenance-free operational lifetime makes them ideal for highly demanding automotive or medical applications. Benefits • High sensitivity with fast response time • High dynamic range • Small SMD package • I2C communication compatible • Digital output • Programmable gain and filltering • Various optical filter options • Integrated configurable amplifier, filter and ADC • Low power comsumption One world.

Do not use in water, alcohol ETA, corrosive gas or under sea breeze. Do not be expose to corrosive substances. Do not drop or apply any mechanical stress. The performance of this device can be affected by ESD. Precautions should be used when handling and installing the sensor. Precision devices such as this sensor can be damaged or caused not to meet published specification due to ESD. Please note that there is limited ESD protection built-in as the device is optimised for low power consumption and low noise operation. Human Body Model (HBM), per JS-001: 2,000 V. Pyroelectric Infrared Sensors should be stored in normal working environments. Solderability will be degraded by exposure to high temperatures, high humidity, corrosive atmospheres, and long-term storage. KEMET recommends that ambient storage conditions are < 30°C and < 60% relative humidity and that maximum storage temperature does not exceed 110°C. Atmospheres should be free of chlorine and sulfur-bearing compounds. Temperature fluctuations should be minimized to avoid condensation on the parts. For optimized solderability sensors stock should be used promptly, preferably within 24 months of receipt. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com SE0214_QGS • 4/17/2020 10 Gas Sensors – QGS Pyroelectric Infrared Gas Sensors, I2C-SMD KEMET Electronics Corporation Sales Offices For a complete list of our global sales offi ces, please visit www.kemet.com/sales.
