ماژول سنسور تشخیص گاز دی اکسید کربن MH-Z19B دارای فن آوری مادون قرمز غیر پراکنده ( NDIR )

Description :
MH-Z19 Carbon dioxide gas sensor (hereinafter referred to as sensor) is a general-purpose, small sensor that uses non-dispersive infrared (NDIR) principle to detect CO 2  present in air. It has good selectivity, no oxygen dependence, and long life. long. Built-in temperature compensation; both digital output and waveform output for easy use. The infrared sensor is a high-performance sensor that combines sophisticated infrared absorption gas detection technology with precise optical path design and sophisticated circuit design.

Specifications :
High sensitivity, high resolution, low power consumption
Provide UART, PWM waveform and other output methods
Temperature compensation, excellent linear output
Excellent stability
long lasting
Resistance to water vapor interference, no poisoning
