915 Generation -Z19 -Z19E IR Infrared CO2 Sensor Module for CO2 Monitor (A)

The -Z19E carbon dioxide sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor. It has two : pin and terminal. It uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air and has good selectivity. No oxygen dependence, , etc.
The sensor is a high-performance sensor made by closely combining mature infrared absorption detection technology with precise optical circuit design and sophisticated circuit design.
High sensitivity, low power consumption stability
Temperature compensation, linear output serial port (UART), PWM waveform and other output methods
long lasting
Anti-water vapor interference, no poisoning
