Electro Optical Components introduces a series of low cost CO2 NDIR sensor modules for gas detection applications including indoor air monitoring, agriculture etc. The EOC-IR300 (link) is more accurate and faster. The EOC-PCL0A2K (link) is the smallest CO2 detector available and is lower in cost.
The EOC-IR300 and the EOC-PCL0A2K are NDIR CO2 gas modules that have a precision light chamber, state of the art electronics and intelligent software. With the help of single light source, dual channel detector, and microprocessor, both modules can accurately measure the gas concentration. Both systems are great for applications like indoor air monitoring, ventilating system, cars etc. The EOC-PCL0A2K (link) is really small (nothing is smaller).
|In the EOC-IR300 Module, (link) temperature compensation is included as well as firmware to null out any nonlinearity. It has all the advantages of NDIR gas detection including good selectivity, high sensitivity, long life and independence from O2 interference. You can accurately measure CO2 using flow through or diffusion.|

EOC-PCL0A2K is really small (10 x 10 x 31mm!!!)
and low cost but it still has all the advantages of other NDIR
products, such as good selectivity, high sensitivity, long life
and is not interfered with when O2 is
present. With the help of single light source, single channel
detector, and microprocessor, EOC-PCL0A2K can perform the gas
concentration signal in different ways. In this product,
temperature compensation has been realized as well as the
revision of the nonlinear relationship. The EOC-PCL0A2K has the
function of self calibration in every 24 hours.
