Carbon Dioxide Measurement Module

The EE89 series carbon dioxide miniature module is designed especially for mass production and OEM applications. The measuring principle is based on infrared technology (NDIR). The EE89 series is maintenance free because of the patented E+E auto-calibration feature, compensating for the effects of aging and therefore warrants outstanding long term stability. The output of the digital interface allows easy signal processing. Contact pads at the edge or contact pins provide multiple ways of mounting the board. Technical data: measuring range ? 0...2000/5000 ppm; outputs ? digital E2 interface; accuracy ? 0...2000 ppm: ? (50ppm + 2% of measuring value), 0...5000ppm: ? (50ppm + 3% of measuring value); and supply ? 4.75...7.5 V DC.
