These include PAS (photoacoustic spectroscopy) CO 2 sensors, NDIR (nondispersive infrared) CO 2 sensors, and EC (electrochemical) CO 2 sensors. Infineon’s XENSIV™ PAS CO2 sensor matches the performance of NDIR and EC CO 2 sensors, while being more affordable and compact, making it the ideal solution for smart home and building automation applications.
The miniature NDIR CH4 sensor SJH is based on NDIR technology that is superior to thermal catalysis and heat conduction technology, and can detect 0 to methane (CH4) concentration. It has the advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and dual beam design.
In particular, relatively large infrared output can be obtained at 3 µm to 5 µm wavelength which is required for CO2 sensors. Therefore, even when it is used for a dualwavelength method sensor (a system which uses not only an absorption wavelength but also a reference wavelength), only one incandescent bulb (single infrared source) is required.
The infrared sensor IR CO 2, with a measurement resolution of Vol.%, provides safe and exact measurements as well as a warning against toxic concentrations of carbon dioxide in the ambient air. For those applications where the reliable measurement of explosive substances and CO 2 is specifically needed, the advantages of both can be achieved by a dual sensor (Dual …
