Winsen MH-410D NDIR CO2 Gas Sensor - UART/Analog Output
The Winsen MH-410D is a miniature NDIR CO2 sensor module compatible with 3.6-5V DC systems, providing both UART serial and analog voltage output for integration into Arduino, Raspberry Pi, ESP32, and industrial control systems for accurate 0-1% volume CO2 concentration monitoring.
Features
- NDIR (Non-Dispersive Infrared) sensing principle for high selectivity and stability, independent of oxygen levels.
- Dual output options: UART serial communication and analog voltage signal for flexible system integration.
- Integrated temperature sensor for real-time thermal compensation ensuring measurement accuracy.
- Low power consumption with an average current draw under 85 mA and a fast T90 response time of less than 30 seconds.
- Compact and robust package (Φ20 x 21.4 mm) designed for long-term operation in HVAC, IAQ monitoring, and process control applications.

The MH-410D utilizes a mature NDIR detection core, integrating an infrared source, optical path, bandpass filter, and detector to measure CO2 concentration based on specific infrared light absorption. This method provides excellent selectivity against other gases and ensures long-term stability and a multi-year operational lifespan. The module’s internal circuitry handles signal conditioning and includes a dedicated sensor for temperature compensation, which corrects for environmental thermal drift.
Designed for direct integration into digital and analog monitoring systems, the sensor outputs data via a configurable UART interface or a linear analog voltage signal proportional to the gas concentration. Its miniature form factor and 3.6-5V DC operating range make it suitable for embedded applications in air quality monitors, smart building controls, and portable safety devices.
