how carbon dioxide sensor module with probe (finger based)

Optical CO2 Sensors

PreSens optical carbon dioxide sensors have a measurement range from 1 to 25 % CO 2, which is perfectly suited for culture monitoring and physiological CO 2 sensor foils for 2-dimensional visualization of CO 2 distributions are available for measurements in trace (0 – 1 %) and medium (1 – 25 %) CO 2 range. Our CO2 sensors do not consume carbon dioxide during the ...

How does an NDIR CO2 Sensor Work? |

These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straight-path design.
