Product Description:
MH-Z1911A Carbon Dioxide Gas Sensor For Fresh Air Systems
Features:
MH-Z1911A carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general intelligent small sensor, using non-dispersive infrared (NDIR) technology to detect carbon dioxide in the air, with good selectivity, no oxygen dependence, long life and other characteristics; Built-in temperature compensation; At the same time with serial output, PWM output, easy to use. The sensor is a high performance sensor made by combining the mature infrared absorption gas detection technology with precise optical path design and sophisticated circuit design.
