The gas chamber is gold-platedDescription
The TX-Z19C carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor, available in both pin and terminal versions. It utilizes the non-dispersive infrared (NDIR) principle to detect CO2 in the air, exhibiting excellent selectivity, oxygen independence, and long lifespan. It features built-in temperature compensation and offers both serial port and PWM output for ease of use. This sensor is a high-performance device that combines mature infrared absorption gas detection technology with precise optical path design and sophisticated circuit design.
