The MH-Z19C Infrared Carbon Dioxide Sensor is an advanced NDIR-based CO₂ measurement module designed for accurate air quality monitoring and environmental sensing applications.
It detects carbon dioxide concentration from 400 to 5000ppm with high stability and reliability. Compared with the MH-Z19B, the upgraded MH-Z19C offers faster warm-up time, improved low-concentration measurement consistency, and reduced power consumption.
Featuring UART and PWM outputs, it easily interfaces with Arduino, ESP32, and other microcontrollers. Ideal for smart HVAC systems, greenhouses, indoor air quality monitoring, and ventilation control applications, this sensor provides dependable CO₂ detection using infrared sensing technology.
Features:
- Advanced NDIR technology for accurate CO₂ detection
- Measures carbon dioxide concentration from 400–5000ppm
- Faster warm-up time under 60 seconds
- Improved reading stability at low CO₂ levels
- UART and PWM output interfaces supported
- Low power consumption design
- Automatic baseline calibration (ABC) support
- Compatible with Arduino, ESP32, and embedded systems
