Leading gas sensing solutions supplier in China www.winsen-sensor.com MH-Z19E NDIR CO2 Module Profile MH-Z19E NDIR infrared gas module is a common type, small size sensor, pins/reversed 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. Applications *HVAC refrigeration *Indoor air quality monitoring *Ventilation system *Air cleaner device *Smart home *School Main Features *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 Fig1.Terminal Fig1.Pins/Reversed Pins Terminal Main parameters Table1.

When placed in small space, the space should be well ventilated, especially for diffusion window. The module should be away from heat, and avoid direct sunlight or other heat radiation. The module should be calibrated termly, the suggested period is no longer than 6 months. Do not use the sensor in the high dusty environment for long time. Leading gas sensing solutions supplier in China www.winsen-sensor.com To ensure the normal work, the power supply must be among 5.0V±0.1V DC rang, the power current must be not less than 150mA. Out of this range, it will result in the failure of the sensor. (The concentration output is low, or the sensor cannot work normally.) During the zero-point calibration procedure by manual or sending command, the sensor must work in stable gas environment (400ppm) for over 20 minutes. Forbid using wave soldering for the sensor. When soldering with soldering iron, set the temperature to be (350±5), and soldering time must be within 3 seconds. We suggest customers to use the way of soldering the socket and plugging/pulling the sensors for easier maintenance.
