Production Description:
MH-Z14A NDIR Infrared gas module is a common type, small size sensor, 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 sensor can do temperature compensation; and it has digital output and PWM output. This common type infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, Precision optical circuit design and superior circuit design.
Feature:

  • Chamber is gold plated, water-proof and anti-corrosion
  • High sensitivity, low power consumption
  • Good stabilitTemperature compensation, excellent linear output
  • Multiple output modes: UART, PWM
  • Long lifespan
  • Anti-water vapor interference, anti-poisoning
