After passing through an optical band pass filter, an IR sensor then measures the level of IR light present, which indicates the CO2 levels in the optical path.<\/p>\n<p>Murata\u2019s CO2 sensor is available in three forms, as a module measuring 67 x 92 x 20 mm (IMG-CA0011-01&lt;0-2,000ppm&gt;, IMG-CA0012-01&lt;0-3,000ppm&gt;), as a packaged sensor for agricultural applications measuring 80 x 125 32mm (IMG-CA), and in a cased package for BEMS applications (IMG-CB), with a sampling probe already attached. In all cases the output is a 0 to 5 V analogue signal.<\/p>\n<p>The sensors are able to perform over a wide operating temperature range from 0 to 50\u02daC and offer a measurement range of 0 to 3,000ppm with an accuracy of \u00b150 ppm + 5% of reading, typically \u00b130ppm + 2.5% of reading.<\/p>\n<p>Power requirement is AC\/DC 24V, or DC 12V, and power consumption is an average of 0.5 W, 2.0 W maximum.
