Production Description:
MH-Z19E NDIR infrared gas module is a common type, small size sensor, pins type or terminal type, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
Feature:

  • High sensitivity,low power consumption
  • Good stability
  • Temperature compensation, excellent linear output
  • Multiple output modes: UART, PWM
  • Long lifespan
  • Anti-water vapor interference, anti-poisoning

Application:

  • HVAC refrigeration
  • Air cleaner device
  • Indoor air quality monitoring
  • Smart home
