Description
The MH-Z19 Infrared CO2 Sensor Module is a high-performance, non-dispersive infrared (NDIR) sensor designed specifically for accurate carbon dioxide (CO2) measurement. With a measurement range of 0–5000 ppm, this sensor provides precise CO2 monitoring, making it ideal for indoor air quality systems, HVAC applications, and environmental control projects.
Using advanced NDIR technology, the MH-Z19 sensor ensures reliable CO2 readings unaffected by humidity or temperature fluctuations. It offers both UART and PWM output options, making it easy to integrate with Arduino, Raspberry Pi, ESP8266, and other microcontrollers. This module is a top choice for smart homes, greenhouses, and IoT systems focused on healthy indoor environments.
