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.
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 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 together in linear series to allow synchronized
sampling across devices.
• 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)
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

Environmental Compliance
All KEMET Gas Sensors are RoHS and REACH Compliant.
Article 33(1) of the REACH Regulation states that manufacturers and importers of articles (products) are required to notify
their customers of the presence of any Substances of Very High Concern (SVHC) in their products exceeding 0.1% by weight
and provide instructions on safe use of the product.
KEMET Corporation reports regarding the Article 33(1) of REACH Regulation as follows:
1. Applicable Product: Gas Sensors (QFC & QFS series)
2. Report for the content of REACH SVHC list:
The product(s) above contains a substance by more than 0.1wt% per product weight that was published in the 8th update of
the REACH SVHC substances (December 19, 2012).
3. Regarding the safety of the gas sensors (Piezoceramic products):
The Piezoceramic that is used in this product becomes ceramic by sintering powder containing PZT as the main ingredient. It
is chemically stable, with minimum risks toward the human body or environment within the intended use of the product. Please
note that risks could occur in the case of inhalation or accidental oral uptake of powder ceramics.
4. Technical product information on the gas sensors (Piezoceramic products):
The manufacturing technique of the “piezoceramic products” whose main ingredient is Lead Titanium Zirconium Oxide (PZT)
has been established, and there is no alternative material that can exhibit superior performance than PZT at this moment.
Please note that the piezoceramic is listed as an exempt on RoHS (2011/65/EU) AnnexIII (7c.1).
5. The responsibility of piezoceramic manufacturers:
Piezoceramic manufacturers report information regarding PZT containment in their products to the customers to obey the
article 33 of the REACH regulation.
