Abstract

AGUILA RODRIGUEZ, G. et al. CO₂ measurement system based on pyroelectric detector. Rev. mex. fis. [online]. 2016, vol.62, n.3, pp.278-281. ISSN 0035-001X.

CO2 concentration sensor based on the infrared (IR) absorption is presented, by using a pyroelectric detector the sample absorbed IR radiation is obtained and the CO2 concentration is calculated, system capabilities, sensibility, repeatibility and, time response of developed system are studied, results show that based on a photopyroelectric technique is possible to get an accurate CO2 measurement system.

Keywords : CO2; infrared absorption; pyroelectric detector.
