CO2 Sensor
Detect CO2 in the air using the non-dispersive infrared (NDIR) principle
Application:
Smart HomeProduct characteristics:
High sensitivity, low power consumptionDescription
TX-Z19D carbon dioxide gas sensor (hereinafter referred to as sensor) is a general intelligent small sensor, which uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has good selectivity, no oxygen dependence, long life, etc.; built-in temperature compensation; serial port output, PWM output, easy to use. This sensor is a high-performance sensor made by combining mature infrared absorption gas detection technology with precise optical path design and excellent circuit design.
