Cat No: INGS-LJX-0010 Datasheet
Product Name: Carbon Dioxide Gas Sensor, 400–2000 ppm
Quantities: - +
| Detailed Description | The carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent miniature sensor that uses non-dispersive infrared (NDIR) technology to detect carbon dioxide in the air. It features excellent selectivity, oxygen independence, and long lifespan; built-in temperature compensation; and serial port output and PWM output for ease of use. This sensor is a high-performance sensor manufactured by tightly integrating mature infrared absorption gas detection technology with precise optical path design and excellent circuit design. |
