Carbon Dioxide Sensor
Introduction
The Carbon Dioxide (CO
carbon dioxide concentration in the atmosphere or an
enclosed space, such as a terrarium. The sensing
element uses NDIR (non-dispersive infrared)
technology .
The sensor consists of an infrared (IR) source and an
IR thermopile element. The thermopile element is
covered with a narrow band filter that only passes IR
energy at 4.27 microns; a wavelength that is absorbed
by the CO gas. As CO
2
IR energy 'seen' by the thermopile decreases. The
relationship between the CO
the absorption of IR energy is similar to that of Beer's
Law.
Although calibration of the Carbon Dioxide Sensor is
generally not required, a calibration button allows
users the option of calibrating. A selectable switch on
top of the sensor allows the user to select between two
ranges: 0 to 10,000 and 0 to 100,000 ppm.
