MH-Z19B ndir CO2 sensor for indoor air quality monitoring

Available:In Stock
R$ 1.584,90

Target gas: Carbon Dioxide
Range: CO2(400-2000ppm/400-5000ppm)
Application: HVAC,building ventilation system, indoor air quality monitoring system.

Production Description:
MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 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:

  • Chamber is gold plated,
  • water-proof and anti-corrosion
  • 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
  • Indoor air quality monitoring.
  • Smart home appliances
  • School
  • Air cleaner
