Carbon Dioxide CO2 Sensor

Carbon Dioxide (CO2) Sensor

A carbon dioxide sensor is an intelligent universal, small sensor, using the non-dispersive infrared (NDIR) principle to detect CO2 in the air, with good selectivity and no oxygen dependence, long life. Built-in temperature compensation; At the same time with digital output and analog voltage output, easy to use.
