Description

The MH-Z19E caon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor. It has two products: 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, long life, etc.

The sensor is a high-performance sensor made by closely combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design.

High sensitivity, low consumption,Excellent stability,Temperature compensation, excellent linear output Provide serial port (UART), PWM waveform and other output methods long lasting Anti-water vapor interference, no poisoning.
