AK9700AD

The AK9700AD is an infrared light emitting element (IR LED) with a peak emission wavelength in the infrared absorption band of CO₂.
Compared with the W filament bulb used in the conventional NDIR type CO₂ sensor, it can control the light emission at high speed and can also reduce the current consumption of the CO₂ sensor dramatically by combining with an AKM infrared light receiving element, the AK9710AE, which has quick response performance. In addition, it has a built - in light receiving element for temperature correction, and high precision sensing can be realized by monitoring the luminescence amount. Since the AK9700AE adopts a small surface mount type, it is effective for miniaturizing the sensor. Since LEDs has a much longer life than the bulbs, a highly reliable sensor can be accomplished.
